[Bug 591489] Re: QEMU_AUDIO_DRV set to none by libvirtd in Lucid

[Tristan Schmelcher]

Changing to confirmed since the reporter has provided the requested
information.

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.
