[Bug 1060053] Re: Audio starts working several hours after starting Windows Vista guest

[Dirk Heinrichs]

I'm using libvirt, but here's the kvm command line as taken from "ps
-ef|grep kvm" anyway:

XML domain definition file from libvirt is attached.

No, I don't know exactly when it started happening, since the guest is
only used from time to time. It's been roughly 2-3 weeks ago, but don't
take that for granted.

No, it doesn't happen on linux guests.
