Many Reddit usersreportedthat the newestWindows 10update causes problems for ICH6 and ICH9 QEMU/VIRTIO devices.
Here’s how one user describes this problem:
For those using VFIO/VIRTIO and running this a a guestOS. It appears that the latest version of the HD Audiodriverhas broken audio completely. Will report back after some troubleshooting.UPDATE: After about an hour of troubleshooting, it appears that ICH6 and ICH9 QEMU/VIRTIO devices are completely non-functional. Only workaround (for me) is to revert to emulated Realtek/Intel AC97. Fortunately this actually netted me a performance improvement.
As the OP states, this is a severe issue — the latestaudio driverafter the update is breaking the audio completely.
The user does come with an explanation and some kind of solution. It seems that ICH6 and ICH9 QEMU/VIRTIO devices cannot function properly on the newWindows 10version.
As a result, the only way to make the audio work again was to revert to Realtek/Intel AC97.
Generally, audiodriversare prone to beaffected by Windows 10 updates, and this case is no different.
Also, there aren’t so many workarounds to solve this type of issues, and Microsoft has yet to come up with a solution or an explanation for this particular problem.
