1============================================================== 2Advanced Linux Sound Architecture - Driver Configuration guide 3============================================================== 4 5 6Kernel Configuration 7==================== 8 9To enable ALSA support you need at least to build the kernel with 10primary sound card support (``CONFIG_SOUND``). Since ALSA can emulate 11OSS, you don't have to choose any of the OSS modules. 12 13Enable "OSS API emulation" (``CONFIG_SND_OSSEMUL``) and both OSS mixer 14and PCM supports if you want to run OSS applications with ALSA. 15 16If you want to support the WaveTable functionality on cards such as 17SB Live! then you need to enable "Sequencer support" 18(``CONFIG_SND_SEQUENCER``). 19 20To make ALSA debug messages more verbose, enable the "Verbose printk" 21and "Debug" options. To check for memory leaks, turn on "Debug memory" 22too. "Debug detection" will add checks for the detection of cards. 23 24Please note that all the ALSA ISA drivers support the Linux isapnp API 25(if the card supports ISA PnP). You don't need to configure the cards 26using isapnptools. 27 28 29Module parameters 30================= 31 32The user can load modules with options. If the module supports more than 33one card and you have more than one card of the same type then you can 34specify multiple values for the option separated by commas. 35 36 37Module snd 38---------- 39 40The core ALSA module. It is used by all ALSA card drivers. 41It takes the following options which have global effects. 42 43major 44 major number for sound driver; 45 Default: 116 46cards_limit 47 limiting card index for auto-loading (1-8); 48 Default: 1; 49 For auto-loading more than one card, specify this option 50 together with snd-card-X aliases. 51slots 52 Reserve the slot index for the given driver; 53 This option takes multiple strings. 54 See `Module Autoloading Support`_ section for details. 55debug 56 Specifies the debug message level; 57 (0 = disable debug prints, 1 = normal debug messages, 58 2 = verbose debug messages); 59 This option appears only when ``CONFIG_SND_DEBUG=y``. 60 This option can be dynamically changed via sysfs 61 /sys/modules/snd/parameters/debug file. 62 63Module snd-pcm-oss 64------------------ 65 66The PCM OSS emulation module. 67This module takes options which change the mapping of devices. 68 69dsp_map 70 PCM device number maps assigned to the 1st OSS device; 71 Default: 0 72adsp_map 73 PCM device number maps assigned to the 2st OSS device; 74 Default: 1 75nonblock_open 76 Don't block opening busy PCM devices; 77 Default: 1 78 79For example, when ``dsp_map=2``, /dev/dsp will be mapped to PCM #2 of 80the card #0. Similarly, when ``adsp_map=0``, /dev/adsp will be mapped 81to PCM #0 of the card #0. 82For changing the second or later card, specify the option with 83commas, such like ``dsp_map=0,1``. 84 85``nonblock_open`` option is used to change the behavior of the PCM 86regarding opening the device. When this option is non-zero, 87opening a busy OSS PCM device won't be blocked but return 88immediately with EAGAIN (just like O_NONBLOCK flag). 89 90Module snd-rawmidi 91------------------ 92 93This module takes options which change the mapping of devices. 94similar to those of the snd-pcm-oss module. 95 96midi_map 97 MIDI device number maps assigned to the 1st OSS device; 98 Default: 0 99amidi_map 100 MIDI device number maps assigned to the 2st OSS device; 101 Default: 1 102 103Common parameters for top sound card modules 104-------------------------------------------- 105 106Each of top level sound card module takes the following options. 107 108index 109 index (slot #) of sound card; 110 Values: 0 through 31 or negative; 111 If nonnegative, assign that index number; 112 if negative, interpret as a bitmask of permissible indices; 113 the first free permitted index is assigned; 114 Default: -1 115id 116 card ID (identifier or name); 117 Can be up to 15 characters long; 118 Default: the card type; 119 A directory by this name is created under /proc/asound/ 120 containing information about the card; 121 This ID can be used instead of the index number in 122 identifying the card 123enable 124 enable card; 125 Default: enabled, for PCI and ISA PnP cards 126 127Module snd-adlib 128---------------- 129 130Module for AdLib FM cards. 131 132port 133 port # for OPL chip 134 135This module supports multiple cards. It does not support autoprobe, so 136the port must be specified. For actual AdLib FM cards it will be 0x388. 137Note that this card does not have PCM support and no mixer; only FM 138synthesis. 139 140Make sure you have ``sbiload`` from the alsa-tools package available and, 141after loading the module, find out the assigned ALSA sequencer port 142number through ``sbiload -l``. 143 144Example output: 145:: 146 147 Port Client name Port name 148 64:0 OPL2 FM synth OPL2 FM Port 149 150Load the ``std.sb`` and ``drums.sb`` patches also supplied by ``sbiload``: 151:: 152 153 sbiload -p 64:0 std.sb drums.sb 154 155If you use this driver to drive an OPL3, you can use ``std.o3`` and ``drums.o3`` 156instead. To have the card produce sound, use ``aplaymidi`` from alsa-utils: 157:: 158 159 aplaymidi -p 64:0 foo.mid 160 161Module snd-ad1816a 162------------------ 163 164Module for sound cards based on Analog Devices AD1816A/AD1815 ISA chips. 165 166clockfreq 167 Clock frequency for AD1816A chip (default = 0, 33000Hz) 168 169This module supports multiple cards, autoprobe and PnP. 170 171Module snd-ad1848 172----------------- 173 174Module for sound cards based on AD1848/AD1847/CS4248 ISA chips. 175 176port 177 port # for AD1848 chip 178irq 179 IRQ # for AD1848 chip 180dma1 181 DMA # for AD1848 chip (0,1,3) 182 183This module supports multiple cards.

One is 277over AC-link and another is over the "direct" SPDIF output. The 278implementation depends on the motherboard, and you'll need to 279choose the correct one via spdif_aclink module option. 280 281The power-management is supported. 282 283Module snd-atiixp-modem 284----------------------- 285 286Module for ATI IXP 150/200/250 AC97 modem controllers. 287 288This module supports one card and autoprobe. 289 290Note: The default index value of this module is -2, i.e. the first 291slot is excluded. 292 293The power-management is supported. 294 295Module snd-au8810, snd-au8820, snd-au8830 296----------------------------------------- 297 298Module for Aureal Vortex, Vortex2 and Advantage device. 299 300pcifix 301 Control PCI workarounds; 302 0 = Disable all workarounds, 303 1 = Force the PCI latency of the Aureal card to 0xff, 304 2 = Force the Extend PCI#2 Internal Master for Efficient 305 Handling of Dummy Requests on the VIA KT133 AGP Bridge, 306 3 = Force both settings, 307 255 = Autodetect what is required (default) 308 309This module supports all ADB PCM channels, ac97 mixer, SPDIF, hardware 310EQ, mpu401, gameport.

1009 When the bit 8 (0x100) is set, the lower 8 bits are used 1010 as the "fixed" codec slots; i.e. the driver probes the 1011 slots regardless what hardware reports back 1012probe_only 1013 Only probing and no codec initialization (default=off); 1014 Useful to check the initial codec status for debugging 1015bdl_pos_adj 1016 Specifies the DMA IRQ timing delay in samples. 1017 Passing -1 will make the driver to choose the appropriate 1018 value based on the controller chip. 1019patch 1020 Specifies the early "patch" files to modify the HD-audio setup 1021 before initializing the codecs. 1022 This option is available only when ``CONFIG_SND_HDA_PATCH_LOADER=y`` 1023 is set. See hd-audio/notes.rst for details. 1024beep_mode 1025 Selects the beep registration mode (0=off, 1=on); 1026 default value is set via ``CONFIG_SND_HDA_INPUT_BEEP_MODE`` kconfig. 1027 1028[Single (global) options] 1029 1030single_cmd 1031 Use single immediate commands to communicate with codecs 1032 (for debugging only) 1033enable_msi 1034 Enable Message Signaled Interrupt (MSI) (default = off) 1035power_save 1036 Automatic power-saving timeout (in second, 0 = disable) 1037power_save_controller 1038 Reset HD-audio controller in power-saving mode (default = on) 1039align_buffer_size 1040 Force rounding of buffer/period sizes to multiples of 128 bytes. 1041 This is more efficient in terms of memory access but isn't 1042 required by the HDA spec and prevents users from specifying 1043 exact period/buffer sizes. (default = on) 1044snoop 1045 Enable/disable snooping (default = on) 1046 1047This module supports multiple cards and autoprobe. 1048 1049See hd-audio/notes.rst for more details about HD-audio driver. 1050 1051Each codec may have a model table for different configurations. 1052If your machine isn't listed there, the default (usually minimal) 1053configuration is set up. You can pass ``model=<name>`` option to 1054specify a certain model in such a case. There are different 1055models depending on the codec chip. The list of available models 1056is found in hd-audio/models.rst. 1057 1058The model name ``generic`` is treated as a special case. When this 1059model is given, the driver uses the generic codec parser without 1060"codec-patch". It's sometimes good for testing and debugging. 1061 1062If the default configuration doesn't work and one of the above 1063matches with your device, report it together with alsa-info.sh 1064output (with ``--no-upload`` option) to kernel bugzilla or alsa-devel 1065ML (see the section `Links and Addresses`_). 1066 1067``power_save`` and ``power_save_controller`` options are for power-saving 1068mode. See powersave.rst for details. 1069 1070Note 2: If you get click noises on output, try the module option 1071``position_fix=1`` or ``2``. ``position_fix=1`` will use the SD_LPIB 1072register value without FIFO size correction as the current 1073DMA pointer. ``position_fix=2`` will make the driver to use 1074the position buffer instead of reading SD_LPIB register. 1075(Usually SD_LPIB register is more accurate than the 1076position buffer.) 1077 1078``position_fix=3`` is specific to VIA devices. The position 1079of the capture stream is checked from both LPIB and POSBUF 1080values. ``position_fix=4`` is a combination mode, using LPIB 1081for playback and POSBUF for capture. 1082 1083NB: If you get many ``azx_get_response timeout`` messages at 1084loading, it's likely a problem of interrupts (e.g. ACPI irq 1085routing). Try to boot with options like ``pci=noacpi``. Also, you 1086can try ``single_cmd=1`` module option. This will switch the 1087communication method between HDA controller and codecs to the 1088single immediate commands instead of CORB/RIRB. Basically, the 1089single command mode is provided only for BIOS, and you won't get 1090unsolicited events, too. But, at least, this works independently 1091from the irq. Remember this is a last resort, and should be 1092avoided as much as possible... 1093 1094MORE NOTES ON ``azx_get_response timeout`` PROBLEMS: 1095On some hardware, you may need to add a proper probe_mask option 1096to avoid the ``azx_get_response timeout`` problem above, instead. 1097This occurs when the access to non-existing or non-working codec slot 1098(likely a modem one) causes a stall of the communication via HD-audio 1099bus. You can see which codec slots are probed by enabling 1100``CONFIG_SND_DEBUG_VERBOSE``, or simply from the file name of the codec 1101proc files. Then limit the slots to probe by probe_mask option. 1102For example, ``probe_mask=1`` means to probe only the first slot, and 1103``probe_mask=4`` means only the third slot. 1104 1105The power-management is supported. 1106 1107Module snd-hdsp 1108--------------- 1109 1110Module for RME Hammerfall DSP audio interface(s) 1111 1112This module supports multiple cards. 1113 1114Note: The firmware data can be automatically loaded via hotplug 1115when ``CONFIG_FW_LOADER`` is set. Otherwise, you need to load 1116the firmware via hdsploader utility included in alsa-tools 1117package. 1118The firmware data is found in alsa-firmware package. 1119 1120Note: snd-page-alloc module does the job which snd-hammerfall-mem 1121module did formerly. It will allocate the buffers in advance 1122when any HDSP cards are found. To make the buffer 1123allocation sure, load snd-page-alloc module in the early 1124stage of boot sequence.

It's possible to force 1658to initialize/use ac97 although it's not detected. In such a 1659case, use ``force_ac97=1`` option - but *NO* guarantee whether it 1660works! 1661 1662Note: The NM256 chip can be linked internally with non-AC97 1663codecs. This driver supports only the AC97 codec, and won't work 1664with machines with other (most likely CS423x or OPL3SAx) chips, 1665even though the device is detected in lspci. In such a case, try 1666other drivers, e.g. snd-cs4232 or snd-opl3sa2. Some has ISA-PnP 1667but some doesn't have ISA PnP. You'll need to specify ``isapnp=0`` 1668and proper hardware parameters in the case without ISA PnP. 1669 1670Note: some laptops need a workaround for AC97 RESET. For the 1671known hardware like Dell Latitude LS and Sony PCG-F305, this 1672workaround is enabled automatically. For other laptops with a 1673hard freeze, you can try ``reset_workaround=1`` option. 1674 1675Note: Dell Latitude CSx laptops have another problem regarding 1676AC97 RESET. On these laptops, reset_workaround2 option is 1677turned on as default. This option is worth to try if the 1678previous reset_workaround option doesn't help. 1679 1680Note: This driver is really crappy. It's a porting from the 1681OSS driver, which is a result of black-magic reverse engineering. 1682The detection of codec will fail if the driver is loaded *after* 1683X-server as described above.

Remember, the idea is to get a number that causes us 2106 to just busy wait for as many WaveFront commands as possible, 2107 without coming up with a number so large that we hog the whole 2108 CPU. 2109 Specifically, with this number, out of about 134,000 status 2110 waits, only about 250 result in a sleep. 2111sleep_interval 2112 How long to sleep when waiting for reply (default: 100) 2113sleep_tries 2114 How many times to try sleeping during a wait (default: 50) 2115ospath 2116 Pathname to processed ICS2115 OS firmware (default:wavefront.os); 2117 The path name of the ISC2115 OS firmware.

If mmap is used on such architectures, turn off this 2235 option, so that the DMA-coherent buffers are allocated and used 2236 instead. 2237delayed_register 2238 The option is needed for devices that have multiple streams 2239 defined in multiple USB interfaces. The driver may invoke 2240 registrations multiple times (once per interface) and this may 2241 lead to the insufficient device enumeration. 2242 This option receives an array of strings, and you can pass 2243 ID:INTERFACE like ``0123abcd:4`` for performing the delayed 2244 registration to the given device. In this example, when a USB 2245 device 0123:abcd is probed, the driver waits the registration 2246 until the USB interface 4 gets probed. 2247 The driver prints a message like "Found post-registration device 2248 assignment: 1234abcd:04" for such a device, so that user can 2249 notice the need. 2250 2251This module supports multiple devices, autoprobe and hotplugging. 2252 2253NB: ``nrpacks`` parameter can be modified dynamically via sysfs. 2254Don't put the value over 20. Changing via sysfs has no sanity 2255check. 2256 2257NB: ``ignore_ctl_error=1`` may help when you get an error at accessing 2258the mixer element such as URB error -22. This happens on some 2259buggy USB device or the controller. 2260 2261NB: quirk_alias option is provided only for testing / development. 2262If you want to have a proper support, contact to upstream for 2263adding the matching quirk in the driver code statically. 2264 2265Module snd-usb-caiaq 2266-------------------- 2267 2268Module for caiaq UB audio interfaces, 2269 2270* Native Instruments RigKontrol2 2271* Native Instruments Kore Controller 2272* Native Instruments Audio Kontrol 1 2273* Native Instruments Audio 8 DJ 2274 2275This module supports multiple devices, autoprobe and hotplugging. 2276 2277Module snd-usb-usx2y 2278-------------------- 2279 2280Module for Tascam USB US-122, US-224 and US-428 devices. 2281 2282This module supports multiple devices, autoprobe and hotplugging. 2283 2284Note: you need to load the firmware via ``usx2yloader`` utility included 2285in alsa-tools and alsa-firmware packages. 2286 2287Module snd-via82xx 2288------------------ 2289 2290Module for AC'97 motherboards based on VIA 82C686A/686B, 8233, 8233A, 22918233C, 8235, 8237 (south) bridge. 2292 2293mpu_port 2294 0x300,0x310,0x320,0x330, otherwise obtain BIOS setup 2295 [VIA686A/686B only] 2296joystick 2297 Enable joystick (default off) [VIA686A/686B only] 2298ac97_clock 2299 AC'97 codec clock base (default 48000Hz) 2300dxs_support 2301 support DXS channels, 0 = auto (default), 1 = enable, 2 = disable, 2302 3 = 48k only, 4 = no VRA, 5 = enable any sample rate and different 2303 sample rates on different channels [VIA8233/C, 8235, 8237 only] 2304ac97_quirk 2305 AC'97 workaround for strange hardware; 2306 See `AC97 Quirk Option`_ section below. 2307 2308This module supports one chip and autoprobe. 2309 2310Note: on some SMP motherboards like MSI 694D the interrupts might 2311not be generated properly.

You might also upgrade your BIOS. 2315 2316Note: VIA8233/5/7 (not VIA8233A) can support DXS (direct sound) 2317channels as the first PCM. On these channels, up to 4 2318streams can be played at the same time, and the controller 2319can perform sample rate conversion with separate rates for 2320each channel. 2321As default (``dxs_support = 0``), 48k fixed rate is chosen 2322except for the known devices since the output is often 2323noisy except for 48k on some mother boards due to the 2324bug of BIOS. 2325Please try once ``dxs_support=5`` and if it works on other 2326sample rates (e.g. 44.1kHz of mp3 playback), please let us 2327know the PCI subsystem vendor/device id's (output of 2328``lspci -nv``). 2329If ``dxs_support=5`` does not work, try ``dxs_support=4``; if it 2330doesn't work too, try dxs_support=1. (dxs_support=1 is 2331usually for old motherboards. The correct implemented 2332board should work with 4 or 5.) If it still doesn't 2333work and the default setting is ok, ``dxs_support=3`` is the 2334right choice. If the default setting doesn't work at all, 2335try ``dxs_support=2`` to disable the DXS channels. 2336In any cases, please let us know the result and the 2337subsystem vendor/device ids. See `Links and Addresses`_ 2338below. 2339 2340Note: for the MPU401 on VIA823x, use snd-mpu401 driver 2341additionally. The mpu_port option is for VIA686 chips only. 2342 2343The power-management is supported. 2344 2345Module snd-via82xx-modem 2346------------------------ 2347 2348Module for VIA82xx AC97 modem 2349 2350ac97_clock 2351 AC'97 codec clock base (default 48000Hz) 2352 2353This module supports one card and autoprobe. 2354 2355Note: The default index value of this module is -2, i.e. the first 2356slot is excluded. 2357 2358The power-management is supported. 2359 2360Module snd-virmidi 2361------------------ 2362 2363Module for virtual rawmidi devices. 2364This module creates virtual rawmidi devices which communicate 2365to the corresponding ALSA sequencer ports. 2366 2367midi_devs 2368 MIDI devices # (1-4, default=4) 2369 2370This module supports multiple cards. 2371 2372Module snd-virtuoso 2373------------------- 2374 2375Module for sound cards based on the Asus AV66/AV100/AV200 chips, 2376i.e., Xonar D1, DX, D2, D2X, DS, DSX, Essence ST (Deluxe), 2377Essence STX (II), HDAV1.3 (Deluxe), and HDAV1.3 Slim. 2378 2379This module supports autoprobe and multiple cards. 2380 2381Module snd-vx222 2382---------------- 2383 2384Module for Digigram VX-Pocket VX222, V222 v2 and Mic cards. 2385 2386mic 2387 Enable Microphone on V222 Mic (NYI) 2388ibl 2389 Capture IBL size. (default = 0, minimum size) 2390 2391This module supports multiple cards. 2392 2393When the driver is compiled as a module and the hotplug firmware 2394is supported, the firmware data is loaded via hotplug automatically. 2395Install the necessary firmware files in alsa-firmware package. 2396When no hotplug fw loader is available, you need to load the 2397firmware via vxloader utility in alsa-tools package. To invoke 2398vxloader automatically, add the following to /etc/modprobe.d/alsa.conf 2399 2400:: 2401 2402 install snd-vx222 /sbin/modprobe --first-time -i snd-vx222\ 2403 && /usr/bin/vxloader 2404 2405(for 2.2/2.4 kernels, add ``post-install /usr/bin/vxloader`` to 2406/etc/modules.conf, instead.) 2407IBL size defines the interrupts period for PCM. The smaller size 2408gives smaller latency but leads to more CPU consumption, too. 2409The size is usually aligned to 126. As default (=0), the smallest 2410size is chosen. The possible IBL values can be found in 2411/proc/asound/cardX/vx-status proc file. 2412 2413The power-management is supported. 2414 2415Module snd-vxpocket 2416------------------- 2417 2418Module for Digigram VX-Pocket VX2 and 440 PCMCIA cards. 2419 2420ibl 2421 Capture IBL size. (default = 0, minimum size) 2422 2423This module supports multiple cards. The module is compiled only when 2424PCMCIA is supported on kernel. 2425 2426With the older 2.6.x kernel, to activate the driver via the card 2427manager, you'll need to set up /etc/pcmcia/vxpocket.conf. See the 2428sound/pcmcia/vx/vxpocket.c. 2.6.13 or later kernel requires no 2429longer require a config file. 2430 2431When the driver is compiled as a module and the hotplug firmware 2432is supported, the firmware data is loaded via hotplug automatically. 2433Install the necessary firmware files in alsa-firmware package. 2434When no hotplug fw loader is available, you need to load the 2435firmware via vxloader utility in alsa-tools package. 2436 2437About capture IBL, see the description of snd-vx222 module. 2438 2439Note: snd-vxp440 driver is merged to snd-vxpocket driver since 2440ALSA 1.0.10. 2441 2442The power-management is supported. 2443 2444Module snd-ymfpci 2445----------------- 2446 2447Module for Yamaha PCI chips (YMF72x, YMF74x & YMF75x). 2448 2449mpu_port 2450 0x300,0x330,0x332,0x334, 0 (disable) by default, 2451 1 (auto-detect for YMF744/754 only) 2452fm_port 2453 0x388,0x398,0x3a0,0x3a8, 0 (disable) by default 2454 1 (auto-detect for YMF744/754 only) 2455joystick_port 2456 0x201,0x202,0x204,0x205, 0 (disable) by default, 2457 1 (auto-detect) 2458rear_switch 2459 enable shared rear/line-in switch (bool) 2460 2461This module supports autoprobe and multiple chips. 2462 2463The power-management is supported. 2464 2465Module snd-pdaudiocf 2466-------------------- 2467 2468Module for Sound Core PDAudioCF sound card. 2469 2470The power-management is supported. 2471 2472 2473AC97 Quirk Option 2474================= 2475 2476The ac97_quirk option is used to enable/override the workaround for 2477specific devices on drivers for on-board AC'97 controllers like 2478snd-intel8x0. Some hardware have swapped output pins between Master 2479and Headphone, or Surround (thanks to confusion of AC'97 2480specifications from version to version :-) 2481 2482The driver provides the auto-detection of known problematic devices, 2483but some might be unknown or wrongly detected. In such a case, pass 2484the proper value with this option. 2485 2486The following strings are accepted: 2487 2488default 2489 Don't override the default setting 2490none 2491 Disable the quirk 2492hp_only 2493 Bind Master and Headphone controls as a single control 2494swap_hp 2495 Swap headphone and master controls 2496swap_surround 2497 Swap master and surround controls 2498ad_sharing 2499 For AD1985, turn on OMS bit and use headphone 2500alc_jack 2501 For ALC65x, turn on the jack sense mode 2502inv_eapd 2503 Inverted EAPD implementation 2504mute_led 2505 Bind EAPD bit for turning on/off mute LED 2506 2507For backward compatibility, the corresponding integer value -1, 0, ... 2508are accepted, too. 2509 2510For example, if ``Master`` volume control has no effect on your device 2511but only ``Headphone`` does, pass ac97_quirk=hp_only module option. 2512 2513 2514Configuring Non-ISAPNP Cards 2515============================ 2516 2517When the kernel is configured with ISA-PnP support, the modules 2518supporting the isapnp cards will have module options ``isapnp``. 2519If this option is set, *only* the ISA-PnP devices will be probed. 2520For probing the non ISA-PnP cards, you have to pass ``isapnp=0`` option 2521together with the proper i/o and irq configuration. 2522 2523When the kernel is configured without ISA-PnP support, isapnp option 2524will be not built in. 2525 2526 2527Module Autoloading Support 2528========================== 2529 2530The ALSA drivers can be loaded automatically on demand by defining 2531module aliases. The string ``snd-card-%1`` is requested for ALSA native 2532devices where ``%i`` is sound card number from zero to seven. 2533 2534To auto-load an ALSA driver for OSS services, define the string 2535``sound-slot-%i`` where ``%i`` means the slot number for OSS, which 2536corresponds to the card index of ALSA. Usually, define this 2537as the same card module. 2538 2539An example configuration for a single emu10k1 card is like below: 2540:: 2541 2542 ----- /etc/modprobe.d/alsa.conf 2543 alias snd-card-0 snd-emu10k1 2544 alias sound-slot-0 snd-emu10k1 2545 ----- /etc/modprobe.d/alsa.conf 2546 2547The available number of auto-loaded sound cards depends on the module 2548option ``cards_limit`` of snd module. As default it's set to 1. 2549To enable the auto-loading of multiple cards, specify the number of 2550sound cards in that option. 2551 2552When multiple cards are available, it'd better to specify the index 2553number for each card via module option, too, so that the order of 2554cards is kept consistent. 2555 2556An example configuration for two sound cards is like below: 2557:: 2558 2559 ----- /etc/modprobe.d/alsa.conf 2560 # ALSA portion 2561 options snd cards_limit=2 2562 alias snd-card-0 snd-interwave 2563 alias snd-card-1 snd-ens1371 2564 options snd-interwave index=0 2565 options snd-ens1371 index=1 2566 # OSS/Free portion 2567 alias sound-slot-0 snd-interwave 2568 alias sound-slot-1 snd-ens1371 2569 ----- /etc/modprobe.d/alsa.conf 2570 2571In this example, the interwave card is always loaded as the first card 2572(index 0) and ens1371 as the second (index 1). 2573 2574Alternative (and new) way to fixate the slot assignment is to use 2575``slots`` option of snd module. In the case above, specify like the 2576following: 2577:: 2578 2579 options snd slots=snd-interwave,snd-ens1371 2580 2581Then, the first slot (#0) is reserved for snd-interwave driver, and 2582the second (#1) for snd-ens1371. You can omit index option in each 2583driver if slots option is used (although you can still have them at 2584the same time as long as they don't conflict). 2585 2586The slots option is especially useful for avoiding the possible 2587hot-plugging and the resultant slot conflict. For example, in the 2588case above again, the first two slots are already reserved. If any 2589other driver (e.g. snd-usb-audio) is loaded before snd-interwave or 2590snd-ens1371, it will be assigned to the third or later slot. 2591 2592When a module name is given with '!', the slot will be given for any 2593modules but that name. For example, ``slots=!snd-pcsp`` will reserve 2594the first slot for any modules but snd-pcsp. 2595 2596 2597ALSA PCM devices to OSS devices mapping 2598======================================= 2599:: 2600 2601 /dev/snd/pcmC0D0[c|p] -> /dev/audio0 (/dev/audio) -> minor 4 2602 /dev/snd/pcmC0D0[c|p] -> /dev/dsp0 (/dev/dsp) -> minor 3 2603 /dev/snd/pcmC0D1[c|p] -> /dev/adsp0 (/dev/adsp) -> minor 12 2604 /dev/snd/pcmC1D0[c|p] -> /dev/audio1 -> minor 4+16 = 20 2605 /dev/snd/pcmC1D0[c|p] -> /dev/dsp1 -> minor 3+16 = 19 2606 /dev/snd/pcmC1D1[c|p] -> /dev/adsp1 -> minor 12+16 = 28 2607 /dev/snd/pcmC2D0[c|p] -> /dev/audio2 -> minor 4+32 = 36 2608 /dev/snd/pcmC2D0[c|p] -> /dev/dsp2 -> minor 3+32 = 39 2609 /dev/snd/pcmC2D1[c|p] -> /dev/adsp2 -> minor 12+32 = 44 2610 2611The first number from ``/dev/snd/pcmC{X}D{Y}[c|p]`` expression means 2612sound card number and second means device number. The ALSA devices 2613have either ``c`` or ``p`` suffix indicating the direction, capture and 2614playback, respectively. 2615 2616Please note that the device mapping above may be varied via the module 2617options of snd-pcm-oss module. 2618 2619 2620Proc interfaces (/proc/asound) 2621============================== 2622 2623/proc/asound/card#/pcm#[cp]/oss 2624------------------------------- 2625erase 2626 erase all additional information about OSS applications 2627 2628<app_name> <fragments> <fragment_size> [<options>] 2629 <app_name> 2630 name of application with (higher priority) or without path 2631 <fragments> 2632 number of fragments or zero if auto 2633 <fragment_size> 2634 size of fragment in bytes or zero if auto 2635 <options> 2636 optional parameters 2637 2638 disable 2639 the application tries to open a pcm device for 2640 this channel but does not want to use it. 2641 (Cause a bug or mmap needs) 2642 It's good for Quake etc... 2643 direct 2644 don't use plugins 2645 block 2646 force block mode (rvplayer) 2647 non-block 2648 force non-block mode 2649 whole-frag 2650 write only whole fragments (optimization affecting 2651 playback only) 2652 no-silence 2653 do not fill silence ahead to avoid clicks 2654 buggy-ptr 2655 Returns the whitespace blocks in GETOPTR ioctl 2656 instead of filled blocks 2657 2658Example: 2659:: 2660 2661 echo "x11amp 128 16384" > /proc/asound/card0/pcm0p/oss 2662 echo "squake 0 0 disable" > /proc/asound/card0/pcm0c/oss 2663 echo "rvplayer 0 0 block" > /proc/asound/card0/pcm0p/oss 2664 2665 2666Early Buffer Allocation 2667======================= 2668 2669Some drivers (e.g. hdsp) require the large contiguous buffers, and 2670sometimes it's too late to find such spaces when the driver module is 2671actually loaded due to memory fragmentation. You can pre-allocate the 2672PCM buffers by loading snd-page-alloc module and write commands to its 2673proc file in prior, for example, in the early boot stage like 2674``/etc/init.d/*.local`` scripts. 2675 2676Reading the proc file /proc/drivers/snd-page-alloc shows the current 2677usage of page allocation. In writing, you can send the following 2678commands to the snd-page-alloc driver: 2679 2680* add VENDOR DEVICE MASK SIZE BUFFERS 2681 2682VENDOR and DEVICE are PCI vendor and device IDs. They take 2683integer numbers (0x prefix is needed for the hex). 2684MASK is the PCI DMA mask. Pass 0 if not restricted. 2685SIZE is the size of each buffer to allocate. You can pass 2686k and m suffix for KB and MB. The max number is 16MB. 2687BUFFERS is the number of buffers to allocate. It must be greater 2688than 0. The max number is 4. 2689 2690* erase 2691 2692This will erase the all pre-allocated buffers which are not in 2693use. 2694 2695 2696Links and Addresses 2697=================== 2698 2699ALSA project homepage 2700 http://www.alsa-project.org 2701Kernel Bugzilla 2702 http://bugzilla.kernel.org/ 2703ALSA Developers ML 2704 mailto:alsa-devel@alsa-project.org 2705alsa-info.sh script 2706 http://www.alsa-project.org/alsa-info.sh 2707
