I might be wrong, but it seems to be normal behaviour. It is not
possible (as far as i know) that more than one application opens the
audio device.
To handle this, there are several audio daemons that provide access from
more than one application to a single soundcard (and mix them). Some
common used ones are artsd on KDE and esd (I prefer this one, because
it's small and does not use so much cpu). Gnome has it's own I guess.
I bet if you do a "pkill artsd", the problems with mplayer and xmms are
gone (artsd frees the sound device after a specific amount of time, that
is your 30-60 seconds).
A better solution is to configure mplayer, xmms and other apps to use
arts (Kde apps do this by default). There is a plugin available for
xmms. mplayer can also be configured, see it's manpage...

Ahm. thanks You for explanation.
I will use arts or something then.
