ARC/CEC Stopped Working with TCL 55R615 and Denon AVR1612
I have a TCL 55R615 with Roku TV connected via HDMI3 (ARC) to a Denon AVR1612 receiver. Recently ARC and CEC stopped working. Powering on the TV does not power on the receiver. Volume control on the TCL/Roku remote does not adjust the volume on the receiver. Audio from the TV is coming out the receiver. This all used to work until just recently.
On the TV I go into System -> Settings -> Control other devices (CEC) and no devices are found. If I tell it to search it can't find any devices. All options are enabled (ARC, System audio control, 1-touch play, System standby).
On the receiver I have HDMI Control turned ON. Also, P. Off Control is set to All.
I've rebooted the TV and receiver. I also disconnected other HDMI devices from the TV (Switch, Blu-Ray, Apple TV, Xfinity). Still cannot get the TV to see the receiver.
My TV updated yesterday (9.1.0 build 4917-30). Not sure if this is the cause or not.

I'm glad I'm not the only one with this problem. I'll be curious what they tell you. I've noticed that mine is working intermittently, though mostly not at all. I was suspicious of my HDMI cable, but I tried another one and had the same problem.
