I was excitedly looking at getting one of the new mini displayport > HDMI adapters for my 2009 iMac so I could connect it to my HDTV and not have to worry about a second cable for sound (my iMac is quite a distance from the tv so it's a hassle to have two cables...) but I was disappointed to note that none of the Macs currently sporting a mini displayport actually support audio out through it, even though the displayport standard allows for it. Does anyone know if this is something that Apple could enable through a software update or is it prevented by the hardware configuration of the mini displayports currently in use? If it is something Apple cound enable through software, is it something that Apple would be likely to do? My instinct is that they won't, especially seeing as the most seamless way to connect your Mac to your HDTV currently is via an Apple TV and they're unlikely to do anything that would harm potential sales... Thoughts?
