As someone said, this sound problem happens when using i8x0 based soundcard. Many integrated are based on that chipset, like nForce2 and possibly nForce3. I've circulated this by using sdlquake binaries instead of plain ones, but maybe that ALSA trick works for someone

I've contacted patman something like a year ago regarding this issue and as Windows user he had no idea how to port it, so no, it's not possible if patman doesn't give the source.
