VTX smart audio won’t connect to beta flight.

[Jakedews4]

Ok, I have searched high and low all over the internet for an answer to this and have tried everything I found. This is my first quad build so I’m sure that has something to do with this but for some reason I can’t figure it out. My Eachine tx5258 VTX works well and has a strong signal running through my mamba f405 flight controller to my camera and I get great video, but when I solder the smart audio to the tx1 tx3 or tx6 pads the vtx still refuses to connect in beta flight, yes I did click save and reboot. The smart audio function also works well on everything else besides the vtx in my goggles. I can change and manipulate things in there but when I go to VTX it’s as if I have no vtx connected. It also is telling me the same thing in beta flight also. I’m not sure if my vtx is somehow broken or I somehow missed something on how you need to set it up but this is so frustrating. If anyone has ever had this problem or could help me out I would really appreciate it.

Could you post a picture of what the vtx menu looks like in betaflight?

Sure, this is the ports tab layout and my vtx menu setup. I also added a picture of the wiring if that helps.

Try the NON tbs smart audio setting in the ports tab.

 

[Jakedews4]

I just tried IRC tramp protocol. That has the same effect as TBS smart audio.

ahh.. I just looked up the actual vtx.. that is not a smart audio capable VTX. The audio channel on that particular vtx is for a microphone to transmit sound along with the video signal.
