Sound Card Still Squealing Away

Mates,

The problem is my nForce AC97 Audio Controller on my K7N2 Delta motherboard
is squealing in my ears. It's enough to drive you nuts......... The problem
is more serious than I thought. I can stop alsasound and it still keeps
squealing. I can mute everything in kmix -- same result. I can be in runlevel
3 and it still squeals. It gets better when sound is playing, but then goes
back to squealing when the file is done. YaST has even got buggyirq
configured. I have googled and RTFM and still no luck. What is weird is that
since this is a dual boot machine, I can confirm that there is not problem at
all like this with XP. It has to be kernel or interrupt related. Has anybody
else 'heard' about this issue?? (no pun intended) I can hold down the cursor
keys and scroll through text and the squeal gets more choppy (i.e. goes away
when the key strokes are processed) Literally, my computer sounds like it is
generating Morse code as I type. Here are some additional details on my
config.

The pci bus looks like this:
