Hey set up this FPV system awhile back and have been trying to get it to transmit sound. I have no problem getting the video to transmit but when I hook up a speaker I get nothing. I did not wire the speaker the wrong way as ive tried both.

I really have no idea as I thought it would just be as easy as wiring the speaker to the correct TX cords.

MAybe some electrical limitations?

Heres a list of the things in my system:
11.1V battery
speakers: https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1
RX: https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1
TX: https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

Any help would be appreciated.

Thank you!
