Does any one know here how to setup
Audio with eachine tx801 there is audio mic and supported but no cable is given for setting it up
The eachine tx801 that i found does not support audio so maybe you´ve read something wrong.
Please provide a lInk to where you bought your VTX from.
Maybe it is another Version or something.
Have a look in the vtx instructions to see if the audio support right hand or left hand or both antennas that could be your problem also what are you using to receive the audio
