Mumble not working correctly: I can't hear players, they can hear me

[ILikeTastyBread]

The issue started seemingly at random, lasted for about a week, fixed itself, and then reverted back to not working again a few days later. Basically when I talk, I see the blue/green speech icon and others can hear me just fine. But when others talk, I can see their names indicating they are speaking, but I can't hear them. I have tried restarting Mumble multiple times with no success. Has anybody ever encountered this issue before?

Happened to me.
What happened was I accidentally muted everyone else.

When you're ingame, find a buddy or player who reads chat, mess with your numpad - and + keys until you can hear them.
Can't think of any other reason - if you couldn't hear them then their names wouldn't pop up.

Check your audio output to make sure it's set to the headset you're using. I've also had PRMumble just randomly put its volume down to 0%, so check that too, it's on the same page. You can also have a look at your shortcuts, you could have bound keys to increase and decrease the volume.

Thanks for the help, I'll keep this tips in mind next time. When I launched the game to try out the suggested fixes, Mumble was working again. Hopefully it'll stay fixed, if not I'll try out what you both suggested and let you know if it worked or not. Thanks again!
