I'm with a macbook pro (2009) that has a mini display port. I've already bought a hdmi cable, and external output to a lcd tv is possible.
My question is: I have to manually change the sound output, from speaker to tv, and from tv to speaker when I take off the cable.
Is it possible to automatically transfer - or at least have a small switch next to the clock - the sound from speaker to tv when I connect the cable, and from tv to speaker when I disconnect?
