kvm win8 guest audio is terrible.

[Ram Ramesh]

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 am missing?
