There is an incompatibility with auto suspending. If the server to which
the tunnel is created suspends it's audio device, it will kill the tunnel.

I've "fixed" this by ignoring suspension (the assumption being that it
will automatically open it again).

http://svn.mandriva.com/cgi-bin/viewvc.cgi/packages/cooker/pulseaudio/current/SOURCES/fix-tunnel-protocol.patch?revision=114651&view=markup

This patch should be applied to pa 0.9.8 packages.
