Here are some solutions:

(1) Get the preemptible kernel / latency patch: 
http://www.tech9.net/rml/linux/

(2) Upgrade to kernel 2.5 (In beta stages, not recommended unless you are 
l33t). If you do, enable the prempt option. 

(3) Set userid to root for xmms, and enable realtime priority (in the 
preferences menu) *This is the easiest, best bet*

(4) If you are really hardcore, try compiling xmms, kernel, konqueror, X, etc. 
with -O6. It optimizes at a ridiculous level, some say its risky, probably 
is...

(5) Get a faster computer

Hope this helps,
