I am having serious sound glitches when boosting near asteroids, sound of boost is fine when you are looking ahead, but if you turn around while boosting static gets added to the mix. I suspect doppler effect might have something to do with it.

I run vendetta with "artsdsp -m vendetta". this is the only sound bug i am experiencing. System is Athlon2ghz, 510mb ram, onboard nforce sound card (48000 sampling rate), RedHat9.

What video card? I suspect your framerate goes all out-of-whack when you turn like that, perhaps?

video card is onboard geforce2mx equivalent (this is nforce motherboard). fps is not a problem, as I get up to 120fps in the game.
I was paying more attention to it last night and noticed that it happenes not only when turning, but also near big objects, for example when near the station heading to dock, about 10 meters away from the entrance there's humming. well, that humming is usually mixed with static noise as well. really annoying that.

Ok, it's been noted. I don't know what to do about it yet though.

I expirience this when i set the distance levels too high. just lower(raise?) them a bit, it might help.

Hmm, I just remembered...
There's a setting to change the mixahead buffer amount.
Go into the console and type:
/set snd_mixahead
and see what it's set to. It's probably 0.1.
Try something like 0.15 or 0.2.
/set snd_mixahead 0.15

This will increase your sound latency but it should remove and glitches due to sudden changes in your framerate.
