title_body: Beeper beeps if transmitter is turned of even if it shouldn't I have turned off all beeper sound signals in Betaflight Configurator, but the beeper still beeps if the transmitter is turned off. I thought that that shouldn't happen when RX_LOST was turned off or not paired, but maybe I have understood it wrong? Or is a bug or a problem with my setup in some way?

upvoted_answer: After making sure that you have the RX_Loss beeper disabled, the next port of call would be to check your DShot config.
  
  It may not be the beeper that is making the noise - there is a DShot beacon configuration that allows you to set your ESCs to beep in the case of RX_Loss  - Id recommend you make sure you have that setting correct.
  
  Edit: from your Diff All, it seems that beeper on RX_Loss May still be turned on, though I’m not sure.
