Hmm, not directly, but on the other hand, all soundcard related
problems tend to get worse as you lower the buffersize (--> less room
for timing/etc errors). So OSS-triggering is still the prime suspect. Does
this behaviour still exist? I just tried to reproduce this on my machine
with ALSA 0.6.x's OSS-emulation, but no static whatsoever.
