I have an AppleTV 4K, with the black Siri Remote. Around Christmas time, I switched from a Sony Subwoofer/Receiver to an LG Soundbar with Passthrough (for my projector). Everything worked fine for a few months, then starting around February, about every 5-7 times I power up the AppleTV, Sound Bar, and Projector, the AppleTV acts as though it was never taught how to control sound, and it will either do nothing (except blink the power light), or it will pop up a messages that "Volume Control has not been Configured", with an option to go to settings, which never works. However, as soon as I go into the remote settings, it refreshes and loads that I'm controlling my soundbar over IR. I did reset the AppleTV, and restore from my backup, and reset the remote... several times.

Anyone have any thoughts as to what might be going on?
