Dear Questions,

My sound card [again] doesn't work.  It worked for a while, but at some
recompile or another in the past ... two months, I lost it.  MP3 players
run, but don't give me any errors and no sound comes out.

I'm running:

FreeBSD lambic.physics.montana.edu 4.1-STABLE FreeBSD 4.1-STABLE #34: Tue
Aug 29 10:13:40 MDT 2000
handy@lambic.physics.montana.edu:/usr/src/sys/compile/HANDY i386

This is current 4.1 as of about yesterday.

The relevant lines [I think] from my config:

options         PNPBIOS
device          pcm0    at isa? irq 10 drq 1 flags 0x0
device          sbc0    at isa? port 0x220 irq 5 drq 1 flags 0x15

(PNPBIOS is a red herring here, from a previous attempt.)  I've also tried

options         PNPBIOS
device          pcm
device          sbc


dmesg:

pcm1: <Yamaha OPL-SAx> at port 0x220-0x22f,0x530-0x537,0x388-0x38f,0x330-0x331,0x370-0x371 irq 5 drq 0,1
on isa0
unknown0: <OPL3-SA3 Snd System> at port 0x201 on isa0

I think this "unknown0" is my first sign of trouble.


/dev/sndstat:

FreeBSD Audio Driver (newpcm) Aug 28 2000 19:19:08
Installed devices:
pcm1: <Yamaha OPL-SAx> at io 0x530 irq 5 drq 0:1 (1p/1r channels duplex)


...and I've re-made my sound devices with

	cd /dev; sh ./MAKEDEV snd0

(with a current MAKEDEV out of my src tree, just to make sure.)

I'm out of ideas.  I must have a problem with my config since it's giving
me this 'unknown0', instead of something like 'sb[bleah]' back when it
thought this thing was soundblaster-material.  Any suggestions?  I seem to
go through this about every 8 months.  :-(


Thanks,

Brian
