Hi, does anyone know if you can turn down the volume on the beeps from both drone and remote? Namely the start up beeps and linking beeps?

Thanks in advance

A dab of glue on the piezo buzzer should do the trick.
I used to do the same to muffle the microphone on my XiaoMi Yi cameras.

No volume control on the Spark controller.
I even checked with the DJI Assistant 2 v 1.1.2 hack - no hidden control for it there either.

Hi there, unfortunately, we don't have a way to turn down the volume of the beeping sounds on the aircraft and remote controller. Rest assured that we will keep improving our products to provide more option to our customers. Thank you for your support.
