If your CPU is fast enough to play GTA:SA with full-quality resampler
(I can't test because I don't have this game), you can test this
clicking problem by setting the HQBuffersMax registry entry to
something that is higher than the "normal" number of the concurrent
buffers but lower than the peak number. When the threshold is crossed,
something interesting (I guess, a click) should happen with the sound,
and I also want to know what exactly :)
