[Pkg-libvirt-maintainers] Bug#695371: virt-manager: Virtual machine does not support sound

[Singer Michael]

Package: virt-manager
Version: 0.9.4-2
Severity: important

Dear Maintainer,
The virt-manager has in a VM configured via GUI no sound support. The VM is configured with the audio device ac97 and SPICE (see the XML config file).

In the log file of virt-manager the following entry when starting the VM is created.

virt-manager.log:
[Fr, 07 Dez 2012 16:36:25 virt-manager 7970] DEBUG (cli:83) Uncaught exception:
Traceback (most recent call last):
  File "/usr/share/virt-manager/virtManager/console.py", line 518, in _channel_new_cb
      self.audio = spice.Audio(self.spice_session)
		RuntimeError: could not create SpiceAudio object

By the way, if I have the VM only with qemu-kvm start working the sound. Use the command:

kvm \
 -name sidutest2 \
 -net nic,vlan=0,macaddr=12:A1:00:12:02:09,model=virtio \
 -net tap,vlan=0,ifname=tap1 \
 -drive if=virtio,file=./siduction-12.2.0-rc2-kde-amd64.img,media=disk,cache=unsafe \
 -soundhw ac97 \
 -m 3072 \
 -pidfile /var/tmp/tap1_5900_sidutest2.img.pid \
 -boot order=d \
 -vga qxl \
 -spice port=5900,addr=127.0.0.1,disable-ticketing \
 -device virtio-serial \
 -device virtserialport,chardev=spicechannel0,name=com.redhat.spice.0 \
 -chardev spicevmc,id=spicechannel0,name=vdagent \
 -daemonize \
spicec -h 127.0.0.1 -p 5900

Here is the XML config file in my virtual machine that has the problem with the lack of sound.

What can I do that gets the VM sound support? Is this a bug in virt-manager or a misconfiguration on my part?
