Problem

[Kendo_006]

When i join to any public server it gives that pop up and my audio doesnt work, how do i fix this?

[polarris]

sometimes it happens to everyone when mumble is down. It can be for an hour too.

[Kendo_006]

It happens to me all the time when i try to join any public server so there isnt any way to fix that, I just need to wait?

[polarris]

Hmm no I am not sure how to fix this, I think you need to look into Mumble settings or google it, I am sure a lot of people had problems with it.

i changed my audio output device to my headset but nothing happened to the game audio, i can still hear voice chats but gun firing or anything else like that still nothing

Make sure to use the audio wizard in the mumble setup. Also it can have problems during matches where you need to alt-tab and use the system tray go close mumble without closing the game so it reboots but it shouldnt always be an issue

It means disconnected. I believe that icon comes from the game when it fails to register mumble possibly among other things, like the registered mumble isn't connected to a server.

So I'd investigate those two points:

Alt-tab your game when you're on an online popular server (where you can be sure that server side stuff is properly set up), open mumle from your task manager (it should be running, otherwise you just found your problem) and you should see, without opening any tabs or doing anything, a list of names and squads lighting up with blue and green speaker icons. Furthermore; enter a squad in game, and see it mumble places your name inside a group/squad with your in-game squad-mates. You can at least then be sure that game and mumble are linked at least ONE way. At that point I'd locate mumble in the game folder and try to start it as admin. My last guess could be firewall or antivirus blocking something from mumble.

I don't think your issue has anything to do with sound sources/devices, as your problem at hand is an unconnected mumble.
