    Ok, pretty new to the Mac side of things. I got my MBP about 3 weeks ago I think. I got a mini display to hdmi adapter (off ebay, so this may be the problem). I hooked it up to my laptop and tv and it took me a while to find the mirroring box but I got that working so what's on my computer pops up on the tv. I go to play a tv show, and the sound is just on my computer. I went under system pref and sound but only "internal speakers" is available for the output. Am I doing something wrong? Or do I just have a cheap adapter?

    Thanks,
    Dallas

    Although HDMI supports both video and audio, Mini DisplayPort does not.

    You will have to run a dedicated line for audio. ;)

    Displayport supports audio, but apple has to impliment it. Which they have not yet.
