Hi all, I'm attempting to set up a 5550e so that the rear audio, which is coming from a computer, can be used as a hot mic source with VOX. (rear PTT is not needed). I have wired the RX audio to pin 12 (RX Audio) and pin 16 (Ground) and the TX audio to pin 11 (TX Audio) and pin 12 (Audio Ground).
In this configuration, the RX Audio comes into the computer as a line-level input as expected but I can't seem to get the TX audio working. I'm thinking of moving the TX ground to a regular ground pin like 18, but I believe there are also settings in CPS for GPIO that need to be set for this to work. Can anyone provide some clarification on this?
Another thing I have been trying to figure out is where or not it's possible to have the front microphone remain functional when needed.
