--- Comment #2 from Tobias Jakobi liquid.acid@gmx.net 2008-10-27 18:26:42 --- Well, I seem to get the issue (partially resolved) by throttling the CPU frequency to 1GHz (usually 2.2GHz, it's an Athlon64). I've also enabled VSync with nvidia-settings.
This lets long audio samples play without truncation, but now mouse input is a bit laggy. I'm trying to figure out a good combination of VSync and CPU speed to get this running.
Leaving this open, since it might be fixable by other means.
