Audio bugs and glitches

[Revenge2K]

I was wondering.
Does anybody else experience pops and short short cut offs when playing audio?
when I listen to music I hear the music go off beat a little and maybe pop or drop a little (like WAY less that a fourth of a sec).
Does anybody know what's causing this problem? I'm using the GNU/Linux version.
If so.. can somebody tell me how to fix it because I notice it does it with all audio and even some in videos.
