Symptoms are that +you will hear a lot of clicking and popping sounds, like a geiger counter, +coming out of the PAS even when is not playing anything. + +Probing problems: Since the SB16 uses the same IRQ and addresses for +the different drivers, some of the snd dirvers will not be probed because +the kernel thinks there is a conflict. Until a real solution is implemented, +to get all the snd drivers to work, immediately return(0) to the haveseen() +call in /sys/i386/isa/isa.c on your local copy.
