Actually, I think it is working as intended. A channel without input defaults to the center.
You can set a default value for the channel in betaflight, away from the center (1500). So it will not beep on RX loss.

<p>After making sure that you have the RX_Loss beeper disabled, the next port of call would be to check your DShot config.</p>

<p>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.</p>

<p>Edit: from your Diff All, it seems that beeper on RX_Loss May still be turned on, though I’m not sure.</p>

Perhaps you could expand your answer to explain *why* you think this would solve the problem?

Beeper beeps if transmitter is turned of even if it shouldn't

# Beeper beeps if transmitter is turned of even if it shouldn't

(Asked by: username_0 on 2020-04-18)

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?

I found the problem: RX\_LOST was disabled, but RX\_AUX wasn't. I have the beeper set to beep if i center a swich, and since that is the default in Betaflight, the beeper turn on because it thought the switch was in that position.

I opened an issue about it here:
<https://github.com/betaflight/betaflight/issues/9717>
