[linux-audio-dev] question re: hammerfall cards

[j.c.w.]

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.
