TCL - 49" Class - LED - 4 Series - 2160p - Smart - 4K UHD TV with HDR Roku TV
I can NOT get the visuals to synch with the audio (ie lip synch issues).
I have (obviously) tried adjusting the delay under the settings for the Beam on the app, but that only makes it worse.
It renders watching tv/movies unwatchable.
Anyone else experiencing this/any ideas?

The thing is that the Beam TV audio-out is working just fine with so many other brands of TV already.
Quite obviously it's the actual TV that processes the audio and sends it out through the HDMI-ARC port. So it's really whether the TV is doing that in a timely manner for the Beam to then play the audio it receives.
It's perhaps notable that the Beam is already working well with plenty of other TV brands, so this might perhaps be an issue with some TCL TV models and that a firmware/software update maybe required.
I don't think anyone can yet jump to any conclusions, as these things sound like some further investigation maybe required here by both TCL and Sonos.
I doubt anyone can yet say what's causing the lip-sync delay, never mind answering your question of "when is this going to get fixed?' ...simply because these matters are only just now being reported and investigated here.
Presumably some enquiries need to be made with TCL too as it seems other people are reporting similar issues with their TV's and other peripherals... as shown in these few 'example' links below:
This one mentions problems with a HDMI control board in the TV...
And there appears to be quite a few hits when you search google for 'TCL Roku TV and HDMI-ARC problem'.
