As far as I can tell, all apps are affected. Before I used this
patchset, only some apps were affected. With the old patchset,
everything is perfectly smooth except when the system is under heavy
load, I can here some faint cracking in the sound which was mostly
fixed by raising priorities and switching to a CK kernel, I believe.
But I'm not sure.

I'm not using winealsa or other hacks, I always think it should work
without hacks. I'm not using PULSE_LATENCY_MSEC because it seems to
freeze some games during sound init. And it was also only a remnant of
the old workaround I had to use before. So it's removed for quite a
while now.

I guess that some more configuration option might have an impact.
First, there's a recommendation to increase kernel sound buffers to
2048 (instead of default 64) when using pulseaudio, so I did this. I'm
also using not quite default pulseaudio configuration.

So, I'll bundle up a package of these including the logs. It may take
me a few days, tho.


Thanks,
