ATC sound

I have a problem with the ATC sound. If I use loudspeakers I only hear the sounds of engines, switches, environment, but not ATC orders. With the headphones if I hear the ATC. I have tested the speakers with other programs and they work fine. Sometimes the ATC sounds through the speakers, but other times it doesn’t and I don’t see the reason. Does anyone know why it could be?

Especially if you have USB headphones or use the loudspeakers using an optical connection (SPDIF) check that you assign something else than “default device” in your sound settings.

In MSFS you have two settings to do so, one is for communication, the other for sounds. Set both to your soundcards loudspeaker device and you should be fine normally.
