I recently bought a Mac (new user) and are having a torrid time trying to make the speaker input work from a headset. I've tried two different sets so far and no luck. I've played with the sound input settings but it still only picks up sound from the built in input. This is annoying users I speak to on Skype since it picks up sounds from my whole room, house and even the cars driving by outside. Any ideas what to do? Or what headsets do you folks use for Skype or Ventrillo chat that actually works?
