I do have a "mute" setting on TS3 that disables the TS3 mic while I'm talking in game but then unmutes it when my DayZ talk button isn't pressed. I was told sometimes this can overtake the DayZ setting... so I turned it off. Still didn't work. I was told if I started DayZ too soon after TS3 then sometimes that can happen- so I tried every combination I could think of including no TS3 and it still doesn't work.
