This looks kind of strange. And it prevents your 2nd serial port (sio1) 
from working too.

I thought everything on the PC card controller side used shared 
interrupts now, typically on irq 10. Did you have to frob anything to 
get it working?

Hmm. I don't really know what the current state of the pcic support is 
(mine Just Works), but I know some people with TI chipsets have problems.

I /think/ that in that case you might need:

hw.pcic.intr_path=1
hw.pcic.irq=0

in your /boot/loader.conf, but I'm not really the person to ask about 
this stuff. Warner is, and he tends to hang out over on -mobile.

Of course, the other approach is to disable devices and/or remove cards 
and check the sound stuff with as close to a "bare" machine as possible, 
and see if that works.

If it does, add stuff back slowly until you find what is causing the 
issue, and then figure out why :-/

If it doesn't, try some alternative hardware - it's cheap enough.. :-)

Cheers,
