This is a possible solution if your REALTEK rear panel sound stops or cuts out for no apparent reason after an update or a system crash. It may not work for everyone but is worth a try!

1. Open Realtek Audio manager

2. Set the speakers to quadraphonic (even though you have 5.1....)

3. Open 'sound effects' and change the environment to 'room'

4. Hopefully your sound should now be restored

Good Luck!
