Comment 27 for bug 1580459

I have been able to stop this from happening by recompiling my kernel without SND support. If you can live without sound in your host (it is still there in your guest if you pass through the sound device of your card) then try removing SND support from your hosts kernel. You can also try blacklisting the snd module and snd-hda-intel instead of removing it from your kernel if they are modules. I have not had a crash from a shutdown in a couple of months after removing SND from my hosts kernel. In my mind that points more of a finger at idea that the root of the problem has to do with binding/unbinding of the device.

Chris, for your HDMI sound issue there are a couple of things that might help. I would have that issue immediately if I was using a certain virtual network card in the guest. Using virtio as your network driver helps quite a bit, however it would still mess up on me every now and again. In order to fix everything, I switched it over to MSI signalling from IRQ on the sound device in Windows 10. I also switched the graphics card driver over to MSI and have to switch them each time one of the nVidia drivers gets an update.
