  I know next-to-nothing about Xen, but I'm guessing something is
still using the sound card, and the system won't let you unbind
something which is in use.

  As Patrick Flaherty suggested, try unloading the kernel module(s)
which contain the driver for your sound card.  I'm guessing that would
be:

	rmmod ens1371

  If that works, then try the echo command.

  If you get back "Device or resource busy", then the driver can't
unload because it is in use.  Look for programs that use sound and
which might be holding a sound device open.  Sound servers in
particular (artsd, esd, jackd).
