Funny, I have just tried this with Teamspeak. I also have a Galaxy Nexus, but find that if I join on my PC for listening to communications, then join with my Phone to act as a mic, it says "Too many clones connected" or similar. Could you tell me how you use the phone to talk, but your PC headphones/speakers to listen to comms and also the game sounds? By the way, I installed the Teamspeak app for Android and am connecting through that for my mic. Perhaps you just found a way to make you phone a mic? What is your setup?
