There's no technical reason why this shouldn't function flawlessly, I have no idea why Apple doesn't document it one way or another. This is frustrating because I have a screen whose HDMI port has to stay in use by another device, and my only means of getting audio and video to it otherwise is through the full sized DP port. I know several users here successfully utilize these mini-DP to DP adapters (like this one: ) can anyone test if this type of connection will successfully pass audio? Does the Apple Sound Settings utility still detect the TV in question as an audio output option, as it does using the HDMI adapters? When I go into Preferences -> sound -> output, there is not option to select for the hdmi, just the internal speakers. However, the sound goes through my laptop speakers and not through the tv. There seems to be no information on whether mini Displayport to Displayport adapters can also pass audio. I can connect my tv to my macbook pro through a HDMI cable and the picture shows up perfectly. However, Apple only specifies that audio is available via Mini Displayport to HDMI adapters. So we know that Displayport supports audio pass-through as well as video, and that support for audio out of the mini-displayport was added to recent Macbook models (which I have). Techies, I'd be grateful for some sage advice.
