Default output for TV after standby / Sony 1000xm4 / Display behaviour

[albinoblue]

Hello,

I recently got a WiiM Ultra, but so far my enthusiasm is somewhat limited. Perhaps that will change once I find solutions to the following issues:

1. Bluetooth headphones (Sony 1000XM4):
   Is there now a proper solution for using these, or can anyone recommend a good Bluetooth adapter?
   
   
2. Default output for TV after standby
   After listening to music with the headphones in the evening, when my wife turns on the TV the next day, the Ultra switches to the ARC input as expected — but the sound still comes through the headphones. This happens even though the ARC output is set to Cinch in the settings, and it makes no difference whether the headphones are plugged in or not.
   Is there any way to set a default output or restore a standard configuration after standby?

1. Display behaviour:
   When listening to music, it’s useful to see artist and track information on the screen, while for TV the VU meter is more relevant.
   Is it possible to set the display to change automatically depending on the input channel?

Thank you in advance.
