Today I installed KVM/QEMU/virt-manager, and after starting a VM, I found that in virt-manager I can't hear audio, but if I use spicec, I can hear the audio, So I digged a little bit, and found that to hear audio in virt-manager, I have to enable either pulseaudio or gstreamer of net-misc/spice-gtk manually. I think for most desktop users, they want to enable audio for Virtual Machine, so we could enable gstreamer by default. This should be no harm and can save people a lot of time.

OK, thanks, I got it.
