I have mentioned before, every time after a new firmware update, the user should;
1) Turn off the TV.
2) Turn off the main switch the TV is connected to, remove the power plug too.
3) Wait 15-30 minutes for the TV's PSU to discharge any left over current.
4) Reconnect your TV, turn it on in sequence of source > external audio (if available) > TV.
Also as for your Shield, after several updates you should once in a while do system reboot on it as well - just like what you'd do with your phone.
Lastly, eARC and ARC doesn't always work 100% of the time. You should accept this flaw by now.
1) & 2) & 3) Yea, normally after firmware update, i will "reboot" the TV by turn off and drain out the power
4) i also got unplug everything and reconnect to initialize the handshake.
FYI, I did time to time reboot my shield TV like 2~3 days and the netflix app got loading/buffering issue (stuck at 25%) which require Shield to reboot.
The issue now i still having is Video signal goes black screen with Audio signal still running.
This only happened on
the connection of Shield TV connect to Soundbar Q950T then connect to LG CX.
I might wanna try change the HDMI cable 2.0 (provided in the soundbar) to HDMI 2.1 between STV and Soundbar to test again see.
So far Xbox series X and nintendo Switch which connect direct to LG CX i do not notice the issue (touchwood)
