    I have the 2009 Mac Mini and was wondering if the mini display port has audio output. Does anyone know? I just want to minimize the amount of cables going to my tv.

    I don't believe that Apple supported audio over mini-DisplayPort until the MacBook Pros released earlier this year. I think from that point on any Macs released with mini-DisplayPort then supported audio over it. I believe in your case you need a separate audio cable.

    Everything my research discovered is that the early and late 2009 mini's don't support audio over mini display port.

    I even tried it with no go.

    So I'm running optical out to my AV reciever and mini display port to HDMI for video.

    For a second audio option I'm going to leverage the "zone 2" feature of my AV reciever.

    I'm fairly sure that the 2009 Mac Mini (Mac Mini 3,1) will shove audio through the mini DP output -- if you're converting to HDMI and have the right cable. Technology/CBLMDPHDMI/

    Note that not all HDTV HDMI inputs handle audio input; this is actually a good thing for sources where the audio is carried separately.

    Mini 2009 does not have audio over MDP - it simply isn't in that iteration of the 9400m chipset.

    Thanks for the responses. Right now I'm just using a 3.5mm jack into my tv. I dont have an av receiver yet. I just wanted to see if I could get rid of that 3.5mm jack and then when I purchased an av reciever I could just use the optical out on my hdtv.

    In terms of getting the audio out of mdp, would it be a matter of a firmware upgrade or does the port in these machines just not have the power to move audio?

    Yes, the audio ports are dual analog/digital (optical). Just plug in a mini-Toslink cable and it'll work.

    No, a firmware update will not fix your gen Mini. The NVidia chipset simply does not have audio over MDP.
