[libvirt-users] Cannot get Sound-Output via pulseaudio

Hi, i am currently trying to get my qemu-bashscripts to run via libvirt. It took some time but my first VM seems to work okay. My main problem is Sound. I run a pulse audio service and when starting the vm via Commandline it sends sound to the pulseaudioserver just fine However when i start the vm via libvirt i cannot get any sound output, pavucontrol shows no connected application. When looking at the /var/log/libvirt/<vmname>.log i can see that the vm is started with ‚QEMU_AUDIO_DRV=none‘ . How can i set this to QEMU_AUDIO_DRV=pa ? Hope someone might help me. Cheers
