Solving playback issues

[Craig_in_NC]

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.

Adding to initial post..

ESPN, NFL Network are OK.

FS1 - same problem

Using Roku Ultra

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.

All works perfectly now
