Hi,
ok, obviously there have been enough problems regarding $SUBJECT.
I don't think that all bug reports on ML are really one, though.
So, please check the following if you have encountered this problem.
****
1. For playing through SPDIF, you need to use the 3rd device,
namely,
% aplay -Dhw:0,2 foo.wav
or alternatively
% aplay -Dspdif foo.wav
For ac3dec, you don't need specify -D option (except for model 33; see
below)
2. There are many different models with the same CM8738 chip.
And the configuration is a bit different on each model.
The model number can be checked via /proc/asound/cards.
(My sound card has model 37, BTW.)
The spdif has been tested only on model 37 and 33, so far.
If your chip has another model number, please let me know.
The model 33 has a bug on AC3 mode.
If this happens, try to specify the pcm device explicitly,
for example, like below for ac3dec:
% ac3dec -C -Dhw:0,2 foo.ac3
i'm trying to fix this problem now..
3. Don't turn on "IEC958 Out To DAC" switch.
This is necessary only when WAV and FM must be mixed.
4. Check whether "IEC958 In Phase Inverse" is correct when you'll
receive signales via SPDIF.
5. It seems that the dip switch on board has priority for the
selection of digital i/o, coax or optical.
When you use coax i/o and it doesn't work, check the h/w setting
together with "IEC958 5V" switch.
6. Please read doc/CMIPCI.txt.
****
If the same bug still remains, please report the symptom together with
the dump of /proc/asound/card0/cmipci and the model number of your
card!
ciao,
Takashi
