Brand new 2021 Series 6 Roku TV and Alto 8i soundbar. All of the sudden the Roku remote no longer controls the soundbar even with CEC on. I have also seen some intermittent lip sync issues. Any advice on how to fix this.
Thanks for the post.
Please be aware that Roku device remotes do no support external non Roku device controls.

I have the same problem.
TCL TV & TCL Alto 8i are the same brand.
mine is back working again and the lip sync issues went away when I purchased a faster (8K) HDMI cable. Hope that helps.
