My HP envy 4-1115dx has no sound and the error is "Bluetooth Audio device has a driver problem".
I tried uninstalling and reinstalling the driver and still have no sound. All current updates are installed.
Actually it was acting a bit wierd yesterday, during audio playback there were times that it sounded very fuzzy and "scratchy" if that can describe it accurrately. It then went back to playing normally. One time it was a music playback and the other it was a youtube vid.
