Subjectkvm win8 gues audio is terrible.
Message-ID<xYDBn-3Np-1@gated-at.bofh.it>
I created a fresh install of debian stretch amd64. In that I created a 
qemu/kvm guess install of win8. It only accepted hda as a valid sound 
card. All others show us without drivers. So, I am limited to only HDA 
as -soundhw. Further HDA sounds so broken if I try to test with any 
sound file or youtube video. It is grainy/distorted and outright horrible.

Google searches mentions something about MSI and those approaches are 
simply not accepted by win8. So, I could not use them. I am wondering if 
there is something fundamentally wrong with windows guests or is there a 
setting that I missing.

I have yet to see any virtual machine be as responsive as a host.  The 
latency is especially obvious when playing multimedia -- e.g. audio and 
video.  (I assume video games would be equally bad.)  If you want good 
audio and video performance, install Windows 8 directly on hardware.

Have you tried spice under Virtual Machine manager?  I used to have similar 
problems.  Let all 6 cores run at maximum speed helped some but still occasional 
dropouts in Win7 and Win10.  I switched to spice and audio and video improved 
greatly.
