If have a rather basic question: is it possible to use a USB headset to listen and talk with the SL voice feature and not have the voices you hear come out of the iMACs speaker while the headset is plugged in?
In other words, I plug the headset into a USB port to use my mic, which works, but the voices still come out of the iMAC speaker(s) in addition to the headphones. I would prefer that they only are heard in the headphones.
