Hi,
I'm trying to use mplayer's ac3 passthrough option, with the ALSA drivers, but I
get the following error:
alsa-init: requested format: 48000 Hz, 2 channels, AC3
alsa-init: soundcard set to iec958:AES0=0x2,AES1=0x82,AES2=0x0,AES3=0x2
ALSA lib pcm_hw.c:866:(snd_pcm_hw_open) open /dev/snd/pcmC0D3p failed: No such device
alsa-init: playback open error: No such device
if I do an ll on the /dev/snd/pcmC0D3p the permissions, etc look fine:
- ll /dev/snd/pcmC0D3p
crw-rw-rw- 1 root root 116, 19 Dec 26 17:54 /dev/snd/pcmC0D3p
When I try to cat the file, it gives me the same error, though.
Does anyone have any ideas?
Regards,
Reinier.

The permissions are wrong, unless you run mplayer
as root, which is wrong :)
chown the device to root.audio, put yourself
in the audio group, login to a fresh shell
(you might have to restart X) and enjoy :)

Would that really help much? With the permissions as they are 'others' have
both read and write permissions too, right? (So mplayer running as a
regular user should still be able to use the device...)
Thanks,
Reinier.

Yes, sorry, you are right.
I tried to answer quickly, without really
looking into the specifics of your problem...
What is a possible cause, is maybe that
the correct device driver that goes
with the /dev/ node is not loaded as a
module or compiled into the kernel ?
