My Razer Blakshark mic is not Working

I have this problem since 2 days and i dont find a solution so i ask of your help. So i have a Blackshark V2 with a USB soundcard, i was on discord and tried to talk to my friends but all i hear is how they are wondering why i dont speak, at first i thought they were trolling me but at some point i just checked and there it was, no sound from my mic. The mic is registered in microsoft so it stands there and it is activated i looked at my device manager and even there was nothing wrong all there was, was just no sound. And i also checked the security thing, data security for sound or smt like that but its still not working, so i downloaded the Thx spatial sound App from Razer and somehow i can hear my voive through the mic so i got on Discord again and the same as before everywhere i checked was just silence except the sound app. I looked through at least 20 videos regarding that. My mic and headset are both fine the soundcard and Pc also it just doesnt play my voice.

PLS IF SOMEONE KNOWS EVEN THE TINIEST THING TELL ME. And even if you dont know i thank you for reading all that and at least having tried to help
