Hello, I have been searching everywhere for an answer to this question and I can't believe that anyone else does not experience this problem.

I have a sonos sound system connected with HDMI and selected as audio output in TV (Philips 854 w Android 9) settings, but in the evening I use Bluetooth headphones while girlfriend is sleeping. Before I got the sound system I just turned the headphones on and the TV would automatically mute the speakers and sound would come from the headphones, but now with the Hdmi system the headphones are not automatically connecting. I need to manually go and select audio output to be headphones ever evening for sound to come out of them. Also when I turn them off the TV defaults back to playing trough TV speakers and I have to manually go and sleect HDMI sound system again...

Is there no way to make the fallback the HDMI output? I'm going crazy here....
