Comment 17 for bug 453453

Marking invalid against qemu-kvm. I really don't think the bug is in qemu-kvm. Rather, it must be somewhere among libvirt and pulseaudio.

I have verified that sound works very well in kvm in Lucid and pulseaudio (without libvirt).

I have also noticed that virt-manager in Lucid does not add a sound device by default when creating a virtual machine (you can add one after the fact). I have not gotten guest sound to work correctly under Lucid's virt-manager, though.
