Hi Rob.
Just a question, as I've poked my nose in on this thread.
Kyle's lsmod shows a module (snd-hdsnd-hda-intel) loaded. I can't find such a
module as existing.
would you post the output of lsmod | grep snd
Are you using the same 2.6.26 kernel as Kyle? The latest I've got on my Lenny
install is a 2.6.21, and I'm using an Audigy2 soundblaster card (emu10k1),
and sounds have always worked out of the box on this card. I do know though,
that there can be horrible problems with cards using hda intel.
Nigel.
