So, my buddies and I use mumble. We have for quite some time. I literally have no problems in other games or applications, in fact when I minimize this problem goes away immediately. Basically sometimes and I literally mean sometimes, I can't recreate the problem at will...they just can not hear me on mumble. They can hear me in game VOIP, but it seems as though my mic is muted out of game for some reason. This can last for 10 seconds to 10 minutes. I can't tell if ARMA is muting my mic because as soon as I minimize, everything is fine and they can hear me. This also only seems to occur when I'm actually loaded into a server, the spawn screen seems to work fine, but obviously I spend a lot less time on that screen than in-game. We are absolutely stumped on this, and pretty frustrated since it caused some problems, last night we go the the NWAF and my mic wasn't working the entire time, obviously not the most opportune of times, lol. I would appreciate any help or suggestions. Windows 7 Home x64 Creative X-Fi Gamer Steam, non beta patch.
