This issue was eventually fixed with a firmware update last fall.
The only solution I've found is going to "System" settings and searching for "CEC devices" ... that immediately restores the connection to the sound bar...
So engineers at TCL -- check what that is doing and ensure at startup its initializing the connection to CEC devices correctly.
Thanks for the follow up.
It looks like you are using an outdated Roku OS. Have you tried manually checking for the latest OS update build and then seeing if the issue persists?

Please keep us posted what you find out.

Thanks for the reply...
However, my Roku is set to auto-update and I have ver 11.5 Build 4235. Is there something newer? That update was from yesterday (26 Oct '22).
I'll let you know if the problem persists. It seems that the soundbar doesn't work only after I have the system off for an hour or more ... (something of that order). When I turn it back on I have to:
"Search fo CEC devices"
to get the output back to the Vizio soundbar (on ARC). Otherwise, I get NO sound from either the TV or soundbar.
Weird thing is even before I re-search for CEC devices, the TV says it is outputting to the soundbar via ARC...
Standby for an update tomorrow.
