[Alsa-user] SPDIF out does not work on Audigy

[Reinier B. <rb...@ac...>]

Hi,

I'm trying to get my digital output (SPDIF) to work.  I have a Creative
SB Audigy.  I managed to get the digital output to work with the OpenSource
emu10k1 drivers at sourceforge (http://sourceforge.net/projects/emu10k1/),
but I'm trying to switch to ALSA drivers, because the documentation with
mplayer suggested switching to them for AC3 passthrough functionality.


So, I built the ALSA stuff from CVS, and got the analog part to work fine.
However, the digital output is not working...  Tweaking with the alsamixer
settings does not seem to help.

Currently, the XMMS output plugins I've tried to use are the Esound Output
Plugin 1.2.7, the OSS Driver 1.2.7, and the ALSA 0.9 output plugin (the 
first of which worked fine to produce the digital output with the emu10k1 
driver).

Does anyone have any idea how to get this working?

This is the sound portion of lsmod:

and this is the sound portion of my modules.conf:

# ALSA portion

post-install snd-emu10k1 /usr/sbin/alsactl restore

Finally, some version info:

 - cat /proc/asound/version

 Compiled on Feb 22 2003 for kernel 2.4.20 with versioned symbols.

TIA,
