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.
