HDMI Arc not working on LG OLED 65B46LA

Mine has been working flawlessly ever since I reset the HDMI Arc port by plugging in different device temporarily and by switching to another HDMI cable.

I too have done all the futile rain dances on these forums.

So there are two versions of the WiiM Amp and you can't tell the difference from the outside, except for sending support your serial number.

I can confirm this is the real solution. Absolutely nothing worked, so I contacted support and they ran my serial, confirmed the hardware version, and sent me another unit; the replacement works flawlessly with my LG B4, specifically turning on and off via HDMI ARC and the LG remote controlling the volume of the WIIM.

If you have this issue, stop and contact support.

I have received a brand new unit and now ARC worked plug and play.

Truly exceptional customer support!

Hi everyone, I’ve found an ultimate workaround for the older WiiM models.
The concept is to use Python to listen for volume events from the LG B4 and synchronize them to the WiiM in real-time.
LG B4 <--optical--> wiim
Pre-requisites: Enable 'LG Sound Sync' on your LG B4 so the volume bar becomes active.
Then, run the following Python script.
I’m planning to get a Raspberry Pi to monitor volume events 24/7 and use it as a DLNA server as well. Just sharing this in case anyone finds it helpful!
