Paul,
since you're on the line here (heh heh heh) i have a quick one to run
past you: my asound.state file looks just like what you described, but
i can only seem to get s/pdif out. it doesn't seem to like my dat at all.
now before i killed my win2k partition, i tested all of the hardware and
it was all happy and worked just fine. now it's not. i am using an
aeb8-i and an aeb8-o. does that change anything?
thanks for any assistance you can provide!
j.c.w.
