As I think XEN has no "audio emulation", there's probably no fix other than 
using 
VMware that has an audio emulation. What you are requesting is some magic 
driver 
in XEN that saves the state of the sound card before it reinitializes the card 
for 
the next VM's sound state, preferrably without disturbing sound. As you can 
see, 
that's rather impossible. You could either use the sound hardware from one VM 
only 
and let XEN ignore it, or make the other machines use some higher level sound 
server that's hosted on one machine.

Ulrich
