Hmm, now that you mention it. I think the _BAD_ hissing was indeed only
present on the left channel. It's funny, but with the old Ultrasound
drivers I never had this problem. Someone also suggested removing the
SIMMs and see if they are cause (too slow, faulty). I havent tried that
yet since the GUS had to make room for a NIC (anyone else also in need
of more than 5 PCI slots? :)

Jaroslave, can you confirm this as a hardware bug with the Interwave
chips?
