FIXED w/ 11.0! - TCL Roku R635 10.5 Update broke Dolby Atmos & eARC/CEC Devices?
Edit: Roku ver. 11.0 fixed this! eARC is now active every time I turn on my TV. No more crazy fixes needed. Whomever the Roku software reps were that (maybe read this post) and fixed this, THANK YOU. I wish we could bypass the CS dept and go straight to you next time we have issues.
Edit 2: Confirmed by a Roku CS Rep, they blame TCL for their botched 10.5 update that broke eARC/CEC devices. They sound like they don't plan to fix, so avoid purchasing the R635 AT ALL COST if you have a eARC soundbar. I have posted the email from them in the replys below. Also, just purchased a R646 Google TV for the same price as my R635, and boy am I glad Roku screwed things up, this TV is wonderful!
Edit: Update must be per device. Soundbar works without issue on my older TCL 55S405 10.5.0 4210-30. So something broke with the update on the R635 model. Last day to return my TV is 2/9/22, please fix Roku.
I've been watching Netflix/Disney + for a few weeks with my new TCL R635 and Dolby Atmos Vizio M512a-H6. A couple days ago, I noticed the Atmos logo disappeared from the Netflix/Disney + shows. The green light on the soundbar also did not light up stating its playing in Atmos. I did however notice the TV updated to 10.5 and this is when the issues started. Now every time I go to my audio settings after turning on the TV, it shows Stereo, not Atmos/DTS. You go to your CEC devices, and it shows none. After powering off the TV, I'll turn it back on and it shows Stereo until I do a quick fix below to bring Atmos back. That works until I turn off the TV again, then its back to Stereo. 10.5 seems to have broken Atmos, ARC, or eARC compatibility. Saw on reddit, on these forums, a few other users stated a very similar issue with 10.5. Is anyone else experiencing this? I don't want to have to RMA the soundbar an/or the TV.
I've also updated the soundbar to the latest 1.3.0.7 firmware, played with TV/Roku setting, swapped HDMI cables, factory reset the TV. Nothing for troubleshooting has permanently fixed this. Heck, even the official Roku Dolby Access app wont play the audio in Atmos until a quick fix is used.
My Settings: Audio Output - eARC (Vizio M512a), Digital Output format - Passthrough, HDMI Mode - Auto (recommended)
Note, changing the combination of the above settings all yield the same results.
Quick fixes include
- Refreshing CEC devices
- Changing Digital output format from Auto back to Pass through, or vice versa.
- Unplugging the HDMI cable and re-plugging it into the soundbar or TV.

Another post on this forum with the same issues that explains it a bit better than myself. (Sorry, it said no similar posts when I posted mine)
This issue was eventually fixed with a firmware update last fall.
