No one can hear me on my mumble serever

[Mstanb]

I got a new computer and downloaded mumble and connected to my server and no one could hear me. I saw my thing light up and can hear myself on the configure but for some reason no one can hear me on my own server. I joined another server and everyone can hear me just fine on that, so I dunno what's going on. Any help would be very appreciated. Thanks!
