Predator PH315-53 sound problems after upgrade to Windows 11

I upgraded to Windows 11 and the Bluetooth earphones connected but made no sound. I tried various driver updaters such as Driver Easy and Driver Booster 9 and now the main speakers died too - no sound. Tried various things found on Youtube but nothing seems to work. Any suggestions?
Alternatively - how do I re-install Windows 10 from the recovery partition?
