Having issues on my local live broadcast channels where background sounds come through but, all main dialogue is gone (or very weak). For example, watching a baseball game I hear the stadium noise but not the announcers broadcasting the game. ABC, NBC, CBS & Fox have the problem.
If I switch to my Windows laptop, the sound is perfect. This only started yesterday (Aug 20, 2022). I'm in the Wilmington, NC geography.
I made the mistake of making multiple changes at the same time to both the Roku audio settings and my Yamaha AV receiver. I suspect changing and returning the setting to the original value fixed it. Unfortunately, I cannot exactly tell what fixed it.
