Weird audio output behavior

I have connected my bluetooth headset to the projector once and from now on, each time I switch on my headset for work (connected to my computer), if the projector is on, it keeps showing “Headset Disconnected” and it switch my output audio to Internal Speaker by itself even if it set by default on Aux.
This is a really annoying behavior. No other device in my possession (laptop, smartphone, switch etc) has this behavior…

  • Is it possible to deactivate bluetooth on the projector?
  • Where could I make forget my headphone in the projector parameters?


You can simply forget the headphone on your projector by pressing the BT button for 3sec
