I have a simple power supply for my mic, I don't have any fancy soundboards or anything. My power supply is a Neewer 2-Channel 48V Phantom Power Supply, I'll link it down below. I don't have any software processing going on.

I just wanted to let everyone know I have a perfect setup physically so that's not what I need help with. I need help with my software, my mic has an echo, whenever I have audio playing in fire fox my friends in the call can hear it with crystal clear audio. It's annoying because I have expensive an expensive setup and it sucks to see that it's faulty. I just need someone to tell me how to fix this echo problem, as well as some nice settings to have for my microphone. (PS I dot have REALTEK, I don't even know what that is)
