Hi Everybody!
I'm pulling my hair out over here. I'm stuck on getting my sound working!
setup:
shuttle sn41g2 v1 (fn41 v1 mobo), 512m ram, 120g pata hdd, athlon xp
2200+ cpu, fedora core 6, 2.6.19 (stock) kernel, all the latest yum
updates
this shuttle has the overly complex nvidia SoundStorm2 sound system in
it, the one with all the fancy Dolby Digital codecs. The motherboard
has support for both coaxial and optical spdif outputs, however only
the optical output is actually connected to anything.
I've tried various /etc/asound.conf files, from simple to complex.
I've tried having the IEC958 mixer control muted and unmuted
I've tried adjusting the volume on the IEC958 Playback (it has 3 levels)
I've tried 44100 and 48000 sample rates, as well as no resampling at all
I've tried playing a dvd: mplayer -ao asla:device=spdif -ac hwac3 -
the receiver lights change to indicate a dolby digital stream is
detected, but no sound
Under windows, of course, it works fine :-(
__Does anyone with a Shuttle SN41G2 have their optical output working?__
Thanks,
Gordon
here's the various configurations
