Everytime I load into a server my mic goes to mute and my mic boost shuts off, therefore I have to alt+tab to desktop to turn mic mute off and turn mic boost on. thx for the help.
I had a similar problem - using vent my mic boost was turned off every time I joined a server. after some time I figured out that my mic boost in BF was turned off and that turned off the windows mic boost everytime I joined a server - maybe the same goes for you
