Still seeing issues with latest firmware
I'm running the Channels app on my Apple TV 4K connecting to a Vizio SB36512-F6 and then onto my TCL Roku TV. It appears that in many cases when I start playing a recording, I hear the background sound but the main audio doesn't play. If I stop the recording and start watching it again, the audio starts fine. The shows indicate that they are DD 5.1 so I suspect that the sound bar is not getting the message on how to decode the audio initially. I have the latest firmware (22.214.171.124) on the sound bar.
While I can connect the sound bar to the TV using HDMI-ARC, doing so doesn't let the sound bar handle Dolby Atmos for Netflix or iTunes.
Anyone seen something like this or know how to correct it?
