Mumble doesn't work

[Jhonathas_01]

First, sorry for the bad English, I'm using the translator.
What happened:
I used the game and Mumble normally, until overnight Mumble stopped working. I started by trying to close and restart Mumble, then do it with the game and the computer, but to no avail. I tried to tweak some Mumble settings, but it didn't work out either. I reinstalled the game, and it still didn't work. I do not know what else to do.

Mumble is visually normal (signaling when I speak in loca / squad), but I don't hear anyone and nobody listens to me.
