According to ddt (the gentleman who wrote the linux port),
the kernel in 1.3.8x returns a 2 for stereo sound. This
number is used internally by xquake for a couple of different
things. As you can see above 2.0.x kernels are returning 0,
that's why you get an FPE - it's trying to divide by 0,
and everyone knows you can't do that.

I don't know if ddt has plans to rewrite xquake to fix
this, or it's a sound driver/kernel problem, and not
necessarily the app.

You can get sound in mono however, by setting the
following envar "export QUAKE_SOUND_CHANNELS=1"

There are also 2 other envars related to sound in quake.
These are:
