This sounds familiar.
I've been playing with the Quake sound playback In order to enable sound
without mmap support, Steffen Haeuser advised using a dedicated thread which
writes sound data to /dev/dsp.
It basically works, but the sound is somewhat distorted, and I think the
problem might be similar to esd's .
Where is your backport (or rather patches against 2.4.0-testx) available?
