Guest Sound Over VNC
Dave Allan noticed[1] "when a KVM guest created with virt-manager is running on F10, sound on the physical host stops working. When all VMs are shutdown, sound starts working again. Removing the <sound> tag from the VM XML allows sound to work while the VM is booted." and suggested disabling sound in guests by default.
Daniel Berrange explained[2] "It is complicated :-) In Fedora >= 11 we currently disable all use of sound cards, but this upsets people who want sound ;-P I'm working on a new version of the patch which sets up audio-over-VNC[3], while for SDL allows the host audio backend to be used & configured. I still need to finish my GTK-VNC patches to do the client end of audio over VNC, then it'll all play correctly with desktop audio services via gstreamer/pulseaudio."
