Well while all my drives are PATA, I should mention that I'm not even trying to play mp3s/Ogg files from any of my five drives most of the time. I run a group of Internet radio stations so most times I am listening to them. It's not the server skipping, it's for sure some kind of few second freeze of the mouse/display and the sound stutters at the same time. It's also not just audio in XMMS. I could be watching a video clip in VLC or mplayer and have some of the same results. The picture would freeze for a moment and the audio would stutter for a few seconds, then resume normal playback...and that's even with NOTHING else running but X, Xfce, and VLC. I can "manually" make it worse. As I said before, if I untar an archive like Mozilla or something it gets almost unlistenable and the mouse is constantly freezing as I move it around. > One thing that helped me was to INSURE that the dma for the > hw.ata.atapi_dma and hw.ata.ata_dma where both set to 1. DMA is for sure enabled on all the hard drives, but the optical drive remains in PIO mode. I haven't attempted to play anything from that yet, however. > Also, staying STABLE for me has been advantageous. I have not tried STABLE yet, but if it would help this and wouldn't introduce any new problems I would be happy to give it a try. -Mark
