I use a similar setup on Arch linux and do not experience the problem, 
although, I have found that kernels with the ck patchset disrupt my usb audio 
device somehow and locks it.  Perhaps it could be a kernel/driver problem, 
although I am unfamiliar with the current patchset that mandriva applies to 
its kernel.  See this alsa bug if you think it may be relevant

I used to experience this on Mandriva 2005 with alsa when using dmix on my 
AC97 soundcard.  This also used to happen when the script manager was open, 
which somehow locked soundcards that could not do hardware mixing.  

Assuming you have a soundcard that cannot do hardware mixing, perhaps it has 
something to do with xine's gapless playback, trying to start the new stream 
before the old one is finished.

I see this too, although I have three soundcards in this box.

I'm not sure this was helpful or not, but hopefully gave some clues.
