Re: Newer 10.0 update ruined CEC-eARC audio

After playing around for a bit, I think I may found what’s causing my issue. May help with some of our your issues. I believe when the TCL TV restarts from a Fast TV start, it is not able to make a connection via eARC with my sound bar. If it turns on from a full power off and full power on, it will make an eARC connection. 

To avoid Fast TV Start, I turn disable it under the power settings, as well as the 15 minute low power mode setting under power settings (this will put the TV in standby mode and Fast start it when resuming use). Instead I just have a screensaver kick in after 10 minutes, but keeps the TV on full power mode until I resume use rather than putting it in a standby mode. 

Lastly, even with Fast TV start disabled, it will still Fast TV start within 15 minutes of turning it off. It goes into a standby mode for 15 minutes before fully powering down. So I just need to pay attention if I try to use my TV again within 15 minutes of turning off to double check the CEC/audio settings.

Actually, yes - you (well, your devices):  Roku uses their slow staggered rollouts to user devices (from their beta update servers, which are the default for most devices) to test different builds before wider release.

You "opted in" to their default beta QA program when you purchased and setup your Roku device(s), you just didnt know it.

Ironically they have a firmware beta program, that doesnt seem useful for much other than providing its participants with early access knowledge of forthcoming features/changes.

Even better is that they insist you are not permitted to revert to previous firmware versions, or share the procedure to do so here in their forums - they insist users agreed to have non-functional devices/apps for the duration of whatever time it takes to issue a new build to fix the issues that precluded usage (of course users agreed to no such thing).

My recommendation is that you revert to 9.4 (if available and offered) via the "secret screen" procedure, and then change the update server to release (if configured to beta).

Do you have updated directions on how to revert?

Sounds like your experience is consistent with mine.

The TV is so poor at displaying blacks and gradients anyway... I just want to get something better from a company with a better reputation. I bought the cheapest thing I could find and I got my money's worth.

OK my problem was not the TV nor the AVR! I had set up a Pi 4 (Retropie) which broke the CEC/ARC communication between the TV and AVR for some reason regardless of whether it was plugged into the TV or AVR. So still figuring that out. False alarm.

Not an uncommon problem (of a device breaking other devices functionality due to a bad/buggy CEC implementation).   There are even cables (without connected CEC wires/pins) and devices (to disable/block CEC) for sake for just this reason.

I had an FS4K I had to keep removed from my primary HT setup for several months because it kept clobbering my volume controls and forced auto-mute on the TV/AVR as soon as it was connected (it disabled all volume/volume control functionality).

A newer firmware/"system component" eventually addressed it.
