Rebooting, and setting quake2's sound device to some random non-existing
file "cures" the problem.
Other similar software like mpg123, tuxracer work well.
The hardware is an Athlon 550, sitting on an ASUS K7V-RM motherboard
(VIA KX133 chipset).
Sound device: onboard, via82cxxx driver.
Distribution used is fresh debian woody, updated daily.
The oops looks like this:
--
ksymoops 2.4.3 on i686 2.4.19-pre2-ac4. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.19-pre2-ac4/ (default)
-m /boot/System.map-2.4.19-pre2-ac4 (default)
Warning: You did not tell me where to find symbol information. I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc. ksymoops -h explains the options.

It looks like bad ram, but I can reproduce it any time, and memtest86
finds nothing during a 30 minute run.
2.4.18 plays only noise too, but it does not oops.
