Greetings,
I hope I have sent this email to the correct list, I apologize if I am
in error.
I have a somewhat antiquated motherboard (SOYO SY-K7V DRAGON Plus!) with
an on-board soundcard using the cmipci driver. Audio playback through
the analog output jacks works, as does audio capture from the analog
line-in jack. I really would like to get either of the digital inputs
to work for recording instead though (it has both optical and coaxial
input *and* output jacks available on an optional breakout connector)
however I have so far been unable to do so for either the coaxial or
optical inputs even after having tested several different cables and
external devices as audio sources. Neither recording nor the "monitor"
feature of either digital inputs works. Unfortunately though I have no
means by which to test the digital output other than to look into the
end of a connected toslink cable and verify it indeed lights up.
Initially I suspected my alsamixer settings were simply wrong, however
after extensive testing and searching I have begun to suspect that the
driver is simply not properly recognizing the optional (apparently
somewhat rare) extra i/o expansion header. When I try to record from
the digital input device, arecord outputs the status text, pauses for a
few seconds and then spits out an i/o error. Below, in sections divided
by the "####" bars I have included what I hope is enough relevant
information for someone knowledgeable to help me troubleshoot/fix this
issue. If information is missing I will happily provide it given
instructions on how to find it.
########################################################################
Here is the arecord output:
$ arecord -v -v -D hw:0,2 -f dat test.wav
Recording WAVE 'test.wav' : Signed 16 bit Little Endian, Rate 48000 Hz,

########################################################################
In case its relevant, here is the contents of the cmipci registry file
before I run arecord:
~$ cat /proc/asound/card0/cmipci
C-Media CMI8738 (model 55) at 0xd000, irq 11
00: 02 00 00 00
04: 12 e0 00 00
08: 0c 00 09 00
0c: 00 00 00 08
10: c0 00 00 00
14: 00 00 00 00
18: 00 01 81 0a
1c: ff ff ff ff
20: 10 40 08 00
24: 00 01 00 00
90: 20 09 00 10
And here is its contents while arecord is "hanging" - after I start the
arecord command but before it spits out the i/o error then exits:
$ cat /proc/asound/card0/cmipci
C-Media CMI8738 (model 55) at 0xd000, irq 11
00: 02 00 02 00
04: 12 e2 00 00
08: 0c 00 09 00
0c: 00 00 02 08
10: c0 00 00 00
14: 00 00 00 00
18: 00 01 01 0a
1c: ff ff ff ff
20: 10 40 08 00
24: 00 01 00 00
90: 20 09 00 10
The second contents are the same as while its successfully recording
from the analog input. After the i/o error it reverts to the previous
contents, but the output is always a silent file of exactly 44 bytes
which I assume to be the minimum size for an empty PCM WAV file.
########################################################################
And, last but not least, here is the output of the alsa-info.sh test
script which I hope will contain everything else relevant. Note that
While the current kernel is version 3.12 (vanilla) with both the "#if 0"
lines in the cmipci.c file changed to "#if 1", the behavior as I have
tested it is basically unchanged with the exception of the appearance of
some more S/PDIF switches in alsamixer, and also unchanged from the
stock wheezy 3.2 kernel.
