Overview
When you first enter a lobby in Bioshock 2 Multiplayer your microphone will be automatically turned on. This will annoy most of the players. So this guide is to help you turn off your microphone (Laptop, Computer if you dont want to unplug microphone). There are 2 ways, (2. way is preffered and better):1.Is to go to: Steam in the upper left corner>Setting>Voice>Microphone volume all the way down. Note: this wont turn completely microphone off because as soon something loud happens it will automatically turn off until that loud sound disappears.2. Second way is much better because it will completely turn your mic on all you have to do is go:Steam in the upper left corner>Settings>Voice>Change device>(It will show your mic) and right click at it disable.Have any question write it in the comments.
