I'm a very new user. I'd like to talk to HAL and have him talk back to me but, without listening to HAL through headphones this can't happen. If I use a microphone and HAL talks through my speakers HAL hears himself talking and accepts that as input. He can chunter on to himself for ages, quite amusingly, because he doesn't properly hear what he's saying. Is there any way, other than using headphones, to tell HAL not to listen to himself and only answer me?
Did this make sense?
