    I bought a brand new 2010 Macbook Pro i7.

    I bought this cable:
    http://www.amazon.com/DisplayPort-Adapter-female-Cable-Apple/dp/B0025V2VO0/ref=pd_ecc_rvi_cart_1

    When I connect my MBP to HDMI to the HDTV, I expect to have another output option for Sound in System Preference. Unfortunately, the option is not there. Display works fine, but audio does not route to the TV at all. (I tried this on 2 Sharp HDTVs and also a Panasonic one. No good.)

    What is most confusing is that it has all the correct specs to be HDMI audio compliant, and also the Amazon purchase comments are mixed. Some say audio completely works, others say not at all.

    Has anyone here bought this particular cable and gotten audio working?
    Do I need to install special drivers of some kind?
