To begin, I'd like to explain that I am new to DayZ, I have just purchased the game after waiting quite a while to begin playing. And was very excited to have a game I truly knew I'd pour my heart into to play again. Now, this also means that when this bug occurred, I was disappointed that I could not play the game, but I do understand that bugs happen and I am not upset about this happening to me. I am just happy that I don't believe it is happening to anyone else.
Now, as for the bug:
Whenever I enter a building, my audio completely cuts out. That is not an understatement, I lose all audio of the game and therefore cannot hear players, surroundings, NPCs, and anything remotely close to me happening. This issue can ONLY be fixed from my findings by completely closing and relaunching the game, and beings once again once entering or spawning into another building. This issue can also happen when entering almost anything including the most minuscule of sheds that have a roof above your head.
