I bought this game on PC recently and have not been able to use voice chat at all. I have zero issues on other games, it only happens on DayZ, so I know it's not a problem with my headset. Furthermore, I tried using my webcam microphone, it also doesn't work. I have tried setting my headset as my default input device through Windows and in Steam, neither course of action worked (however, testing my microphone outside of the game does work, so again, it is not an issue outside of DayZ). I've tried re-installing the game, it didn't fix it. I'm honestly at a loss on what to do. It seems like a bug that needs to be patched because nothing I do on my end seems to be working. It has completely ruined the experience of the game for me.
