PLEX on Roku audio issues since latest Roku Ultra update

I tested again after recent Plex server update (1.21.1.3842-b0c7a97d9) and my Roku Ultra seems to be working correctly with my test file but my TCL Roku TV is still getting delayed audio.

Same is true for Roku Media Player - audio no longer delayed on Roku Ultra but is still delayed on TCL TV.

No Roku updates indicated (same version after update a few weeks ago) and Plex and RMP client version is the same on both devices so I’m not sure where any changes may/may not have occurred here or if its an odd fluke. Does Roku do silent updates for bug fixes? I know native Roku devices get updates faster than TCL devices.

Anybody else testing recently seen any changes?
