2. DP can carry audio but mDP can't as it seems. Mroogle for more.

3. DVI (Digital Visual Interface) only carries visual information, so no audio.

If you search through the forums you can easily find your answers as well as more stuff you didn't ask. This is probably why no one has responded. Just searching first man

But to answer your questions........the mini displayport CANNOT carry audio. This is so stupid but it is what it is until apple changes it. To get audio from my MacBook I just use regular desktop speakers. Many poeple have said to use the toslink cables but I don't really need to.
