I'm not at home so I can't send you my exact config files, but I know my
asoundrc looks your original one:
pcm.via82xx {
type hw
card 0
}
ctl.via82xx {
type hw
card 0
}
These lines are in my modprobe.conf:
alias snd-card-0 snd-via82xx
install snd-via82xx /sbin/modprobe --ignore-install snd-via82xx &&
/usr/sbin/alsactl restore >/dev/null 2>&1 || :
remove snd-via82xx { /usr/sbin/alsactl store >/dev/null 2>&1 || : ; };
/sbin/modprobe -r --ignore-remove snd-via82xx
There were some settings on the MythTV general setup screen. I can't
remember them off the top of my head, but I'll post them when I get home.
You probably have already seen this, but in alsamixer there are three items
labeled something like IEC958. The first one needs to be checked, the
second one (IEC958 Output I believe) should be unchecked and the one with a
slider should be all the way down. I believe I turned all four of those DXS
sliders up.
My audio setting in xine is set to Passthrough.
