Bad Quality Mic on Desktop app?

Hi, I've noticed my mic is really bad quality only on one server and only on the desktop app? The browser version works fine but it's a pain in the butt to use as push to talk doesn't work. I have an AT 2020+ and I've also tried my blue snowball and razer kraken headset. All have the same problem on that one server?

I've tried teamspeak and Skype and everything is fine. Does anyone have a fix? I don't own the server so I can't play with settings but I miss having push to talk! All my drivers are up to date and my pc is updated. Windows 7 currently and windows 10 same issue.

TL:DR Tried three different mics and all have awful quality on the main server I'm part of but browser version is fine? Help!
