Description of problem:
I apologize in advance if this bug has already been filed.  I have
seen a few bugs here regarding the snd_intel8x0 driver but did not
believe they were directly related to this bug (which has just popped
up in the latest kernel release, for me at least).

When I fire up an application like XMMS and attempt to play audio, the
application acts like it's shuttling data to the driver (e.g. shows
visualization data) but no sound can be heard.

I checked volume control and unmuted everything.  I tried to play
audio from multiple applications and using both oss and alsa with no
success.  I'm able to reboot into the kernel I was using previously
(kernel-2.6.9-1.724_FC3), and sound works fine.

My machine is an IBM Thinkpad T41.  Here is my lspci output:
