I logged into the DayZ main screen. Before loading in I decided to cook dinner and listen to music. I turned down the master volume to 0. Once i logged into my previous game on the Livonia 5012 NY Official Servier. I loaded into a house outside of Zalesie. I proceeded 100 yards to the closest hunting stand and fund a M70 Tundra. I had win 308 Rounds in my inventory. When putting the rounds in the gun i realized i could not hear the gun loading but could hear the outside noises. Upon curiousity, i stepped outside and ran around and came back. I could not hear my own footsteps inside even when moving. I logged out and logged in to the same problem.
