Teammates cant hear me

I cant seem to talk to my teammates, my mic works perfectly fine, im using Razer Kraken V2 and they work everywhere else but for some reason when i activate my radio, i hold the key down as a i talk and the little radio and local thing comes up on the screen yet my teammates never hear me. In the first Insurgency or DOI when i speak my name comes up with the little radio or local symbl so the team knows who is speaking, but here when i press the key my name pops up for a second and then goes away even if im still holding down the push to talk. Radio and Local stays up on my screen until i release my key but my teamates cant hear me talk this has been going on since the first Alpha
