Greetings,

  I'm trying to get ac3 passthrough working on my media pc.  However
when i try and open /dev/snd/pcmC0D3p i receive a no such device error.
I noticed a few not really resolved answers in the archives so i figured
I'd post again. The devices exist in /dev/snd and /proc/asound/dev and
playback and recording function correctly now (even sound via the
optical connection to the receiver). I've read through all the online
help i could find and am still stumped =/

It looks like it's comming from the -ENODEV return in emufx.c,
but i don't know enough about alsa internals to figure it out yet.

setup is  an sb audigy, connecting via the external optical connector
 to a denon dolby/dts/*  receiver.

As part of trying to figure this out, i used mplayer with the oss
api isntead of alsa9,  (mplayer -aid 128 -ao oss:iec958:AES0=0x87 -ac hwac3 -fs -dvd 1)
this produces an incredibly LOUD clicking/screaching noise from the
receiver.


root # cat /dev/snd/pcmC0D3p
cat: /dev/snd/pcmC0D3p: No such device

boobtoob root # ac3dec -C
Using PCM device '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
snd_pcm_open: No such device
Output open failed

It certainly seems like something should be on minor 19..

root# more /proc/asound/devices

modprobe stuff:
options snd cards_limit=1
options snd-card-0 extin=0x3fff extout=0x1fff
options snd-emu10k1 extin=0x3fff extout=0x1fff


any help would be appreciated,

thanks,
