Hi,

Ever since I updated my S95B 65" from update 1622 to update 1651, the TV incorrectly defaults to TV speakers but with a visual bug on startup. This means I can no longer control the volume through CEC until I change the sound output even though it shows the sound output to be correctly outputting through my AVR.

My setup: Samsung S95B QD-OLED TV, Arcam AVR550, and Chromecast 4K with Google TV. The Chromecast is plugged into the AVR.

My AVR powers my floor standing speakers. I never use the TV speakers.

I use the TV remote to control the AVR's volume via CEC. I have setup the Chromecast remote to also control the TV's volume (IR) so that the TV changes the AVR's volume via CEC same as the TV remote.

Expected behaviour: At startup, using the TV remote or the Chromecast remote should change the AVR's volume via CEC.

Behaviour: At startup, the whole setup outputs sound via the AVR but when I try to change the AVR's volume via TV CEC, either using the TV remote or the Chromecast remote, the TV speakers volume changes instead.

Upon further investigation, I use the TV remote to access quick settings. The sound output selection shows that it is outputting via the AVR (which it is, but I can't change AVR volume via CEC). But if I press on the selection using the OK button once to change sound output, the selection flashes from AVR to TV Speakers and back to AVR again, as if it's a visual bug. With this visual bug out of the way, I can change the volume using the remotes as usual (expected behaviour).

This visual glitch seems to happen often when I start the setup using the Chromecast (TV starts via CEC). The visual glitch may not always happen and sometimes the sound output will falsely show TV Speakers as the startup output instead.

Version 1622 never had this inconsistency. No matter how the system boots up, the TV can communicate with the AVR via CEC without needing to "change" the sound output once first.

Any help is much appreciated. Any questions please ask and I'll do my best to answer.

Edited: Clarification and further findings.

Edit 2: I'm working around this issue by setting the Chromecast remote to control volume via Auto (CEC) rather than Samsung TV (IR). At least the Chromecast knows that the AVR is supposed to be the default audio device, so I can now use the Chromecast remote to change volume consistently again. The volume steps are slower to respond but I can live with that. Plus, since this is CEC, and the remote connects to the Chromecast via Bluetooth, I can adjust the volume without relying on IR, meaning I no longer have to point the remote at the TV to adjust volume. All in all it turned out for the better. Still, I'd rather be given the choice than being forced to find a workaround, Samsung.
