Audio Alert AP74

[erickmei]

Dear all,

I have a technical question. I have a Dynon 100 (firmware version 5.4.3), with AP74. I tried to install the audio alert system through the AP74. I opened the D25 and I found the pins installed, 3, 4, 16 and 17. Then I installed a wire to the pin 25, in order to connect sound in the aircraft intercom system. I installed a 10K potentiometer, it not worked. No sound. What I need to do?

Sincerely,

Let's start with the basics: are all of the other functions of the AP74 working?

Also, perhaps try not utilizing the pot, just for the time being. That will allow audio to be at its full volume (the pot is used to attenuate the volume).
