Dota 2 is detecting another mic in my system that I cannot remove or disable and using that for the default in-game voice. I'm using it for line to winamp for visualization effects on pandora. Dota 2 really needs a select mic input option. I'm not sure why this suddenly stopped working and it decided to choose another mic, but I can't talk to others in game until t his is fixed. I have checked the steam options, they had no effect.
