Does anyone know how I can mke the ATC sounds louder, I can hardly hear it. I have moved the ATC slider in sounds fully to the right but still it is very hard to hear. I was hoping maybe a tweak in the cfg file or something like that. Many thanks.

If your ATC slider is all the way up, try turning the other sounds down so ATC will be relatively louder. Once the balance is right, just turn up your speakers to an overall level you like.-Gary
