The audio on my phantom 3 standard not working. No known reason. Is there something I rnay of turned off.
Which audio are you referring to?
Sound to cell phone recording.
There is no such thing that I know of.
When I record flying thru control app. Video and sound.
That is a function of your phone, not the app or the Phantom. The Phantom does not record audio.
There is a feature in DJI GO 4 (see below) that allows sound from your mobile device to be recorded with the cached video. That setting is not available in DJI GO (3) though.
