2020 TCL 55R635 TV (OLED-Like) - Brightly-lit, Pinpoint, Tiny Stars!), Vizio Sound Bar
If this is happening with both direct
connect to TV and to Soundbar it
would seem the issue points to either
your DVR and or cable from your DVR.
Repeatable errors are much easier to troubleshoot.
If it is random, it's going to be much harder
to get a pinpoint on what is actually happening.
It's happening over 50% of the time, both with the internal speakers the the sound bar.
This happened/is happening with the first use of the DVR since the Thirty-Sixty-Four Update.
What are the odds that it's a cable issue at the same time the Firmware Update lands inside my P50?
Prior to the Update, this audio problem wasn't there with
this DVR going back to the M40... even the VP322 (Plasma).
If I were a betting dude, I'd slide the whole pile of chips to the center table that it's the
3064 Update that is the cause. (Uh-oh. House security just showed up.)
