Hello all,

Thanks for the replies.

lsmod shows my sound modules loaded (at least I think that's all of them).  And
if I run aplay /dev/dsp as root, I still get a "no such device" error, so
permissions are not the issue.  Check out my modules and see if I'm missing
something.

Again, I'm running debian-unstable with kernel 2.6.9.

My mythtv user is in the audio and video group.
