Microphone not working when using app

Hi, when i use my micophone, either the one in the headset or the intergrated mic (which works fine in calls). I press the push to talk button on the app, and the little blue circle next to my name begins to light, but when i talk no one can hear me (tryed to log on ts on my pc to verify). Then i tryed to reinstall the app, which removed the "client flooded" issue, but the mic is still not "recording" my voice, and no one can hear me
