2 Brief Notes on C-Media 8338/8738/8768/8770 Driver
8 Front/Rear Multi-channel Playback
9 ---------------------------------
13 DACs, both streams are handled independently unlike the 4/6ch multi-
14 channel playbacks in the section below.
22 - The first DAC supports U8 and S16LE formats, while the second DAC
24 - The second DAC supports only two channel stereo.
51 control switch in the driver "Line-In As Rear", which you can change
52 via alsamixer or somewhat else. When this switch is on, line-in jack
60 4/6 Multi-Channel Playback
61 --------------------------
63 The recent CM8738 chips support for the 4/6 multi-channel playback
66 When the multi-channel is supported, the driver name has a suffix
67 "-MC" such like "CMI8738-MC6". You can check this name from
70 When the 4/6-ch output is enabled, the second DAC accepts up to 6 (or
72 formats, the 4/6-ch playback supports only the same condition for all
73 channels. Since the multi-channel playback mode uses both DACs, you
74 cannot operate with full-duplex.
77 in alsa-lib. For example, you can play a WAV file with 6 channels like
80 % aplay -Dsurround51 sixchannels.wav
96 Line-In Mode
97 an enum control to change the behavior of line-in
98 jack. Either "Line-In", "Rear Output" or "Bass Output" can
102 are output to line-in jack.
103 Mic-In Mode
104 an enum control to change the behavior of mic-in
105 jack. Either "Mic-In" or "Center/LFE Output" can be
108 channels (channels 5 and 6) are output to mic-in jack.
111 -----------
113 The CM8x38 provides the excellent SPDIF capability with very cheap
116 The SPDIF playback and capture are done via the third PCM device
117 (hw:0,2). Usually this is assigned to the PCM device "spdif".
122 % aplay -Dhw:0,2 foo.wav
128 % aplay -Dspdif foo.wav
132 The playback and capture over SPDIF use normal DAC and ADC,
136 To enable SPDIF output, you need to turn on "IEC958 Output Switch"
138 so-called S/PDIF). Then you'll see the red light on from the card so
140 The SPDIF input is always enabled, so you can hear SPDIF input data
141 from line-out with "IEC958 In Monitor" switch at any time (see
144 You can play via SPDIF even with the first device (hw:0,0),
145 but SPDIF is enabled only when the proper format (S16LE), sample rate
153 Mix analog PCM playback and FM-OPL/3 streams and
154 output through SPDIF. This switch appears only on old chip
157 Note: without this control you can output PCM to SPDIF.
161 IEC958 In Select
162 Select SPDIF input, the internal CD-in (false)
166 SPDIF input data is loop back into SPDIF
175 configuration with hardware dip-switch.
177 IEC958 In Monitor
178 SPDIF input is routed to DAC.
180 IEC958 In Phase Inverse
181 Set SPDIF input format as inverse.
184 IEC958 In Valid
188 stream through analog line-out.
192 ----------------------------
194 The driver supports raw digital (typically AC3) i/o over SPDIF. This
196 access it via alsa-lib. See alsa-lib documents for more details.
199 turned off so that non-audio data is heard from the analog line-out.
201 "IEC958 Loop". The switches are resumed after closing the SPDIF PCM
204 On the model 033, AC3 is implemented by the software conversion in
205 the alsa-lib. If you need to bypass the software conversion of IEC958
211 ----------------------
218 In addition to the standard SB mixer, CM8x38 provides more functions.
219 - PCM playback switch
220 - PCM capture switch (to capture the data sent to DAC)
221 - Mic Boost switch
222 - Mic capture volume
223 - Aux playback volume/switch and capture switch
224 - 3D control switch
228 ---------------
230 With CMI8338 chips, the MPU401-UART interface is disabled as default.
246 --------------
258 ------------------
261 joystick_port=1 module option. The value 1 means the auto-detection.
262 If the auto-detection fails, try to pass the exact I/O address.
268 ---------------------
270 The registers are shown in /proc/asound/cardX/cmipci. If you have any
