Yes, I heard them, too. Mplayer works, but as soon as aRts gets involved, the 
problems arise. Juk can be configured to use arts or akode for playback. When 
I configure arts, the audio playback skips frames. Akode on the other hand 
works for me.

Noatune skips frames, too.

OK, I tested it with longer mp3s and oggs and frames are skipped :-(. I also 
tested it with a longer wav and that doesn't work either. Short ones (like 
KDE_Startup.wav) seem to work, though.

I'm not familar with them either.

Thanks for the hint!
