terratec dmx xfire 1024 ac3

[Guido Bakker]

hi,

i'm trying to use the optical out of my terratec dmx xfire 1024 with an ac3 
stream.

root@thebox:~/alsa/alsa-tools-0.9.0rc6/ac3dec# ./ac3dec -C test.ac3
Using PCM device 'iec958:AES0=0x2,AES1=0x82,AES2=0x0,AES3=0x2'
ALSA lib pcm.c:1719:(snd_pcm_open_conf) Invalid type for PCM 
iec958:AES0=0x2,AES1=0x82,AES2=0x0,AES3=0x2 definition (id: iec958, value: 
cards.pcm.iec958)
snd_pcm_open: Invalid argument
Output open failed

i'm getting this error, any ideas?

i'm running alsa rc6.

I'm now stuck to 2ch ac3 only.

i guess the file is corrupt or you forgot byte-swapping.

what about running ac3dec without -C option (i.e. analog two
