tnx for the info, I use ogg sometimes so this is good to keep in mind (although I think I never experienced the fps drop yet). I did experience extremely dull/low-pitched tones when playing one of my games which has alot of ogg soundfiles. I never bothered to check what is precisely was, though I feeling that it may have been the lack of ogg codec as well. That was a while ago though, now it is solved I think.
