This came in from mav@ and I wanted to re-post it here to see if anybody 
else has experienced this, or can confirm the issue?

No. I don't know them. Can you ping them for me? You should easily see
unneeded sound interrupts by yourself in `systat -vm 1`. Process using

hw.snd.verbose sysctl set to 4.
