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.
30 The rear output can be heard only when "Four Channel Mode" switch is
35 When "Four Channel Mode" switch is off, the output from rear speakers
43 front one) and was so excited. It was even with "Four Channel" bit
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
82 For programming the 4/6 channel playback, you need to specify the PCM
92 and use the interleaved 4 channel data.
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

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.

230 With CMI8338 chips, the MPU401-UART interface is disabled as default.
