I too am experiencing this bug. Looking at the libvirt source code, it specifies QEMU_AUDIO_DRV=none whenever using VNC for graphics. The comments say this is because it tunnels audio over the VNC connection. /* QEMU implements a VNC extension for providing audio, so we * set the audio backend to none, to prevent it opening the * host OS audio devices since that causes security issues * and is non-sensical when using VNC. */ ADD_ENV_LIT("QEMU_AUDIO_DRV=none"); However, the VNC viewer that virt-manager uses apparently doesn't support the audio extension. That's why sound is broken.
