Controller push to talk PC

I can not get the push to talk to work on my Afterglow controller. I’ve checked to make sure its the controller and not mic. When push to talk is off or I’m using it on my mouse it works fine. I’ve tested one other controller and it did work but the controller is not mine so I cant use it. I have tried to rebind it to other parts of the controller like the A, or Y, buttons but those didn’t work either.
