After the latest windows update last week my pc's audio driver suddenly gone missing it's not on the device manager list (im using realtek that comes from my mobo). I tried reinstalling it a few times but when it restarts my pc after installing the driver is gone. I tried to recover my windows to the previous version but it doesn't help.
