I'm not even really sure where to start troubleshooting this. I'm assuming it's likely the vista driver that's giving me issues, but here's the symptoms
playing any kind of media file that has audio (doesn't matter if it's just an mp3, a dvd, divx/mkv video file [altho these have mp3 audio as well usually]) results in a kind of stuttering in the audio track every 30 seconds or so
sometimes it's a bit more often, or sometimes not at all
stuttering isn't quite right, it's almost like it's briefly buffering the audio track. slight distortion, stuttering, etc etc.
I thought initially it was maybe streaming over wireless that was the issue (i WAS having issues with my new N WAP) but even playing a file that exists locally has the same issue
doesn't matter if it's played via mediacenter, windows media player, or Itunes, same result
I've got the most up to date driver for my audio chipset
it definitely never did this with XP
