I doubt this is your issue, but if I reply it could help someone else who is searching about the same problem
I have a very modern Haswell machine that I set up to run KVM, with VGA passthrough for a very modern video card (GTX 970). Since I didn’t care about the performance of the host video, I had installed an ancient PCI card for this purpose (I mean super ancient, like a Matrox Millenium or something like that). With this setup, the audio in my Windows VM stuttered and lagged very badly. As soon as I replaced the host video card, the problem went away. So the takeaway is, just because your modern machine has a legacy (non-PCIe) slot, doesn’t mean you should use it. :-) -Aaron > On Dec 19, 2015, at 1:51 AM, [email protected] wrote: > > Hi, > I have now upgraded virtual machine from win8 to win10 but I have still this > HDMI audio issue. > It seems my linux vm not affected by that. > I use VGA passthrough so not soundhw hda... > Sometimes if I'm lucky I can get back to normal the sound when reinit "NVIDIA > High Definition Audio" device but reboot vm is the best. > I tried different configs in win audio settings but nothing and I haven't > another audio card to check. > This issue appears randomly during session, idle or not... > > Does anyone know please if it's vfio related? > _______________________________________________ > vfio-users mailing list > [email protected] > https://www.redhat.com/mailman/listinfo/vfio-users _______________________________________________ vfio-users mailing list [email protected] https://www.redhat.com/mailman/listinfo/vfio-users
