Weird Apple tv audio issue

This is a weird one … I’m doubtful anyone else has encountered it, but here goes …

My AppleTV HD (15.2) is connected to a Vizio TV; it is the only source.

I noticed that there was audio only from two streaming apps: YouTubeTV and Apple Music.

No audio whatsoever from any other app. What’s more, switching from either of those two audio apps to another caused the audio to stop on both YouTubeTV and Music.

The only cure is to reboot the TV; this yields sound again, but only on those 2 apps.

I have reset the AppleTV … swapped HDMI cables … and spoken with Apple tech support. I currently have an appointment to have the the box checked out. Then I decided to swap in a similar model AppleTV, and had the same problem.

Until my appointment comes I decided to call Vizio. They suggested trying some of the built-in apps. The result: audio from every app I tried.

Weird! But right now I’m thinking this might be some kind of incompatibility between the AppleTVs and the Vizio. Thoughts?

Please follow these steps in order:

Got it! Apparently the Audio Format was changed, possibly during the 15.2 update. I've changed it back to Stereo (because I use the TVs speakers in this case).
