Hi Everyone, I've had Tower 3D Pro since like 2016 and I've never been able to use the voice feature because it just wouldn't pick up anything. I thought it was my computer issue but even after I got my new computer, I still had this issue. I've tried literally everything to fix this issue but nothing worked. Today I accidentally found a solution to this issue and I hope this help out those who are still having this issue. Before you start the game, go to your sound settings and change your output source. (Yes output, not input.) I have portable speakers so I changed into that. Then launch the game. (I started as administrator, IDK if it matters.) Then start the game with whatever airport you want to do. Once the game is fully loaded and you hear the push-back request from the first aircraft, go back to your sound settings and change your output source back to your headset. Here is a YouTube tutorial I did if you need some visuals... Hope it works for you.
