    Can anyone confirm whether the Altaz Mini DisplayPort to DisplayPort adapter carries audio?

    I have emailed the company but they have not responded.

    I ask because I have my macbook air hooked up to a Dell U3011 with the Altaz adapter.

    It drives the display perfectly, but I want to know if this cable connection also carries an audio signal.

    I've looked around online and it seems Apple is not very clear about this subject.

    I would love to be able to hook up the Dell AX510 SoundBar to my Dell U3011 monitor and just have the single Altaz mini DP -> DP adapter carry the video AND audio signals.

    I found this thread on the apple forums which suggests in some cases mini DP -> DP can in fact carry both

    And I found this thread here which implies the sound bar can receive audio from the Dell monitor that is carried through HDMI connections.

    So can anyone here confirm whether the Macbook Air -> Dell U3011 - > SoundBar set up works only using the Altaz mini DisplayPort to DisplayPort adapter?

    The sound bar + its power adapter is around $40, so I'd prefer to know if it works or not before I buy it.

    *Edit: I also found this post , but it is a year old. Not sure if the Macbook Air 2011 handles this port differently.

    So I took a look at my sound settings, and interestingly Lion seems to identify my monitor as a device for audio output...

    It could possibly work I guess?


    I can't be the only one who is curious about mini DisplayPort to DisplayPort audio capabilities, I hope.

    I can confirm mini DP -> Displayport does carry audio and video.
