Here are my settings.
Please not that in "audio" I can either select "Macbook Air speakers" or "external headphones" that's it..
When I select Macbook Air speakers, I only get sound from the laptop's speakers and when I hit any cue button it just layers the sound on top of it...
When I select "External Headphones" I have absolutely NO SOUND coming out from neither my headphones, nor the external speaker. Both these items are plugged into the provided splitter cable from Pioneer...
