Beta 3 fixed it for me as well, last time I ever do an beta update.

Does anyone know how to make a complaint about this issue? Albert seems to have gotten lost.

Hi Albert, are you ignoring our messages? This is getting beyond frustrating

Hi Albert - any update on when this will be fixed?

Hi bigafro ga. think we have to wait for a software update. Don’t think resetting will help. DTS engineer (Albert) - can you confirm this? Thanks

Having the exact same problem. on my iPad 7th generation. no sound on any apps or websites.
