Thanks for the replies guys.

The audio output quality is perfectly fine with the normal 4 channel Paula Noteplayer. It's just when a CPU-dependent mixing Noteplayer is used, the mixing rate jumps around (usually downwards until it hits about 11kHz) as if the emulated CPU was too slow. I'll do some more testing in the next 48-72 hours with other programs (EaglePlayer perhaps, OctaMED SoundStudio, and other Noteplayers in DeliTracker) to see if the issue is specific to DeliTracker.

As I said previously, this was never a problem previously for me, but seems to have recently become a problem. I'm not sure if it's hardware or software. I've tested two CPUs (FX-4170, E-350) so far with the same version of Ubuntu (12.04 AMD64) and FS-UAE (1.3.30 i386). I'll try a Phenom II soon as well.

A possibly related problem is Alien Breed 3D 2 TKG running very poorly on the same system/install, even though SysInfo shows plenty of MIPS to spare, and the DrWhoGenie runs very well, even fullscreen.
