Hi Hans,

I'm hoping there's a simple solution to this
that I've just missed
somewhere along the line. Occasionally something will crash while using
oss emulation and I can't use the sound card until I reboot. I've tried
lsof /dev/dsp and as many other variations as I can think of and I never
get anything (even when sound is playing), which I think is related to
using devfs. I've also tried fuser, and good old visual grep on the
output of ps and nothing is running that would use the soundcard yet I
can't unload the snd-pcm-oss module.
This time it was timidity (which I have promptly uninstalled since this
version seems capable of nothing other than locking up my soundcard),
but it has been mplayer in the past.
Is there some way to restore access to the sound card short of
rebooting?
This is probably one of two things, none is easy to fix.
1. Driver problem. If the driver fails due to a bug, it generally leads to
that the hardware is left in an undefined state. Meaning that there is
absolutely nothing you can do but reboot.
Long term solution is to get a new driver or fix the old one, since you
mention OSS I would propose trying the ALSA drivers. If you need OSS support
there is a compatibility layer.
2. Actual hardware problem. Might be the motherboard but in general it's the
soundcard. It might help to switch pci-slot. Otherwise the only solution is
to get new hardware...

Unless you are experiencing other hardware related problems, lockups, reboots
etc I think driver problems would be the more probable.
