I have linked a cable from my MacBook Air to my TV via HDMI but cannot get volume on the TV. I have gone into preferences-sound but their is no facility to change 'internal speakers'. How can I do this?

If you are using a Mini Displayport to HDMI adapter this should help you. If you are using Mini-DVI to HDMI adapter then you will have to get audio from your headphone port via an external cable because DVI is strictly video.

  • because I am not tech savvy I assume that the little adapter I purchased from Mac Book Air is not sufficient to power audo to TV. Because I cannot change 'audio output' on Mac perhaps it will never work and I will need the eternal speaker via headphone port??? – colin webb Apr 12 '14 at 7:39
