Hi,
I am using the latest alsa drivers 1.0.11rc4 with the audigy 2 ZS notebook
pcmcia card (Vanilla kernel 2.6.16 on gentoo-amd64). If I just use xmms to
play something, with the optical output connected to my decoder, the
decoder detects it as "prologic" and plays it. The channels seem to be
wrong though. But my real concern is getting ac3 passthrough to work.
If I configure xine for a passthrough and play some dvd. All I hear is a
repeated periodic noise. The same happens with "mplayer -ac hwac3
dvd://something". The alsa sound card matrix is not clear about the spdif
output status of this card.
I was wondering if anyone got this pcmcia card spdif out to work. I have
been a linux user for a while, but I am new to fiddling with alsa. At
present, the module:snd_emu10k1 is loaded with its default options. I am
not sure if I should try other options. A search through the mailing list
archives showed that a few people used some patch to get the audigy 2 zs
(the pci soundcard version) to work. But those postings were old, my guess
is the patch should be in the latest alsa by now. I would appreciate any
alsa debugging tips and options that I could try.
I never tested it, so I might not work yet.
I think standard PCM stereo should work, just maybe not AC3.

Are you talking about PCM through optical output? If so,
when I use xmms, the alsa mixer "Front" channel seems to
control all sound output. My decoder plays this on the
front and left speakers. I am not sure if the selection of
speakers is determined by the decoder or by the alsa optical
output. Could you please clarify this? Can you also tell me
if there are any module options that I could possibly try?
Thanks.
Anand
