Hello aviation enthusiast!
I have had an extremely annyoing problem the past few months... The thing is that I can not hear ATC after being idle for a while. If I don' talk to them or press my ptt button once in a while the ATC (RX) stops working and I can not hear anyone. There has been occasions where the ATC told me to go around but I could not hear them because of this issue.
I have noticed now that when I enter Navigraph charts or open google chrome the ATC sound disappears. But when I enter FSX again it starts working (BUT only if I push the ptt button). I read on some vpilot
