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.

Any updates to this issue? I have tried all the suggestion above but still can not get audio using HDMI ARC on my LG B4. Optical works but unable to control volume.

You could use the WiiM Remote Control to control the volume, it works perfectly well for me.
Please turn off eARC on the TV and switch the digital audio output to PCM.

Did that but no luck using LG own WebOS and on my PS5.
Have you already tried the HDMI cable included with the WiiM? Also, there is currently no sound coming out of the TV speakers, correct?
Please try unplugging the power cables from the TV and WiiM, then plugging the HDMI cable back in and turning it back on after at least 10 minutes.
If this does not resolve the issue, please submit a ticket through the feedback section of the WiiM app. A device log will be sent to you.
(Sorry if you have tried everything.)
