Spdif passthrough and sound cards, Output to get

SourceForge.net: xine-user: " This is not a xine problem.
I have xine working with SPDIF AC3 on the following sound cards:-
1) Motherboard based sound card with optical outputs. (snd-intel8x0)
Output from alsamixer:
Card: Intel ICH5
Chip: Realtek ALC650F
(SPDIF works with the Analog to SPDIF [off])
(With Analog to SPDIF [on]) output goes to front analog speaker jack.)

2) A old SB Live (rev 06) (snd-emu10k1)
Card: Sound Blaster Live!
Chip: SigmaTel STAC9721/23
3) An SB Audigy 2 with mini-jack spdif out.
Card: Sound Blaster Audigy2 (snd-emu10k1)
Chip: SigmaTel STAC9721/23

It is a well know fact that SPDIF output does NOT work on all cards that ALSA works with. Some might only be able to get PCM output over SPDIF.

In order to make any progress, we will need to know which sound card and codec you are using.
So, get the 'CARD' and 'CHIP' output from alsamixer.
also, get the output from 'lspci -n | grep 0401'

I might be able to help then."
