    Hey,
    I have a MacBook Pro (15'', Intel Core duo 2.4 GHz, 2GB ram) that I´ve bought in June. Yesterday I upgraded my mac to Leopard and, since then, the built-in speakers haven´t worked. The sound preferences say: "the selected device has no output controls".
    Headphones work pretty well, though.
    Well... I've tried resetting PRAM and SMC, but it did'nt work. I´ve also tried reinstalling Leopard and updating it to 10.5.1. But it didn´t work either.
    So, today I´ve just used the option "erase and install" and reinstalled Leopard, erasing everything from my mac. Well... it didn´t work, and I still can´t make my built-in speakers work.
    Does anyone have any idea about what should I do?

    You need to contact AppleCare technical support or take your MBP into an Apple Store.

    Hello there ..

    I had a similar problem after upgrading last night. I didn't get to the point of reformat / reinstall as I found an easy fix (for my problem anyway!)

    After discovering that whilst my speakers did not work, my headphone-out jack did, I simply cycled that connection a couple of times. Evidently the iBook was fooled into thinking they were still plugged in and had disabled the onboard speakers.

    Good luck. :p
