This also happens on my computer. It's because of the combination of the high
CPU usage resampler. GTA:SA has quite a few secondary buffers, and when enough
of them are in a playing state, the mixer can't keep up. This causes underruns
in the audio, and GTA:SA is apparently written to block if the dsound write
pointer doesn't move quickly enough. If I use the low quality resampler given
in Comment 230, GTA:SA runs fine (unless, presumably, enough sound effects
become active at once and it falls behind again).

This is the same problem. Changing to the low-quality resampler fixes it.

Haven't looked into this yet.

The trace is missing a newline. I added the newline and it stopped crashing.
Audio seems to work, though I'm not familiar with the game.
