Because its seems no one else is responding....

look through the last few week's mail archive at www.freebsd.org/mail

other people are having said problems after someone made changes to the
sound drivers. I'm not sure if its fixed yet.

what i would try:

-cvsup to latest stable
-try removing 'device sbc' from your kernel config

hope this helped
