I might have gotten this wrong, but I think this is by design. Artsd
seems to grab /dev/dsp and hangs on to it, assuming everything that
wants to produce some sounds will use it's API - the idea is to enable
multiple applications to produce sound (or at least access the output
devices), instead of having one OSS application playing and everything
else being locked out. There are two solutions to this problem:
1.) If you're happy with the old way of "one app gets /dev/dsp and
everything else will just have to wait", you can disable artsd
autostarting itself in the kde controlpanel (this will probably mute
kde itself).
2.) With kde comes a wrapper application called "artsdsp". With this
wrapper application you should be able to run any OSS application
through artsd without the OSS app knowing it. The wrapper even has an
ESD compatible mode ("artsdsp esd").
For xmms, there is an artsd output-plugin available.
