I think that the problem is the master volume potensiometer when mission starts is in max position but sound doesnt work you have to turn it left and right again

Thank you @LooseSeal you save me alot of time for search....

Yes I see the messages in the left upper corner I am using srs without problem generally.i noticed in the video that squelch switches stop in on or off position ..mine stay in the middle what ever I do... messing around with switches it worked finally I will update when i ll know the exact reason why thank you for immediate answer

Hi I turn up the volumes I press master I setup the frequencies in the radio but I hear only ground crew and copilot am I missing some button or procedure about the radio?
