oss driver? So a third party audio driver could also be part

Try ogg123.
Which xmms (ogg123) audio output driver are you using? I guess that with
your oss audio driver you could be using
- "oss" Open Sound System driver, using the /dev/dsp device
- "sun" Sun Audio driver for NetBSD, OpenBSD, and Solaris
Use the /dev/audio device.
- "arts" aRts Sound Daemon (when KDE desktop is used).
- "esd" Enlightened Sound Daemon (when GNOME desktop is used).
I'm just using S10-GA-x86, ogg123 (and the "sun" audio output driver),
an ufsdump is running on the filesystem containing the .ogg files, and a USB
keyboard / mouse. There is no skipping with the audio, and no jittery USB
mouse.
The system is ~70% idle during this test:
