I'm having very similar issues with two TCL TVs and it's driving me nuts. I've largely been suspecting the HDMI extenders (with ARC) I've been using to get signal to the WIIM amps in my AV closet, but it's crossed my mind a couple times that it might be the TVs. This thread further confirms the suspicions about the TVs. Not sure exactly what to try next.
HDMI Arc not working on LG OLED 65B46LA

I tried toggling off and on the Auto-sensing of Optical In & HDMI (mentioned in Post #9) and that seemed to work. Will have to try it a few more times to see if that is a consistent work-around.
Another odd behavior I'm seeing in my situation - There is often a very long delay between when I try to change the volume using the TV remote and when it registers on the WIIM amp and ultimately comes through the speakers. When I say long, I mean like 20-30 seconds. I can instantaneously adjust the volume using the app. Just more gremlins with the ARC functionality...

Have you already tried disconnecting the HDMI extender and connecting the TV directly to the WiiM?
In your case, the ARC on the extender may not be functioning properly.
