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-
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
94 There are some control switches affecting to the speaker connections:
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.

137 control via mixer or alsactl ("IEC958" is the official name of
138 so-called S/PDIF). Then you'll see the red light on from the card so
141 from line-out with "IEC958 In Monitor" switch at any time (see
150 Additionally there are relevant control switches:
153 Mix analog PCM playback and FM-OPL/3 streams and
157 Note: without this control you can output PCM to SPDIF.
162 Select SPDIF input, the internal CD-in (false)
175 configuration with hardware dip-switch.
188 stream through analog line-out.

195 can be toggled via IEC958 playback control, but usually you need to
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.

211 ----------------------
214 There are Master, PCM, Synth, CD, Line, Mic and PC Speaker playback
215 volumes. Synth, CD, Line and Mic have playback and capture switches,
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.
232 to enable MIDI support. Valid I/O ports are 0x300, 0x310, 0x320 and

257 Joystick and Modem
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.
264 The modem is enabled dynamically via a card control switch "Modem".
