I have a Windows 11 system running under libvirt/qemu. A recent
Microsoft software update overwrote the audio driver. Device manager
would not let me install the one from the virtio ISO because it had
determined that the "best driver was already installed". But sound
wasn't working.
I solved this by going into device manager and deleting the windows
driver, then adding the viogpudo driver from the ISO manually. After
rebooting the virtual machine, audio was working again.
