Players are no longer able to hear me as of last week. None of my settings changed, no new programs were installed, nada. Out of the blue, players simply couldn't hear me any more. This is despite my microphone working exactly as expected in every other program, and it was working just fine in DayZ for months prior.
I've tried the following:
Setting dedicated inputs for dayZ & steam
Running DayZ as an administrator while it being the only app open
Uninstall of DayZ and full deletion of all associated files before reinstalling
Speaking into a megaphone in game both with PTT and speech detection mode
When I hit push to talk, the mic icon does show up, and I have confirmed DayZ is accessing the correct microphone (all others are disabled) and that the microphone input is at full volume and clearly audible in other all apps, including nvidia's in game broadcast feature where my voice clearly comes through in the overlay.
