    Hi, on my 2009 i've noticed now that after using bootcamp for a bit then booting back into os x that i have no sound available, there's no sound devices in preferences. this is using the line-out jack. any idea why that would happen? rebooting seems to solve it but its kind of annoying. thanks.

    update 2 it's still happening, every time after using bootcamp i have no line-out device in os x. unplugging and replugging the audio cable doesn't seem to help :/

    Sorry, I have no clue what's going on, I have 2 machines w/W7 via Bootcamp and have no issues with sound. All I can say is maybe a clean reinstall of both OS to see if it was software related, but this seems like overkill.

    when it has no output device i looked in about this mac/system profiler and under sound devices it just says Intel High definition with id 0, and no other information. it's like it's not even loading the driver for the sound card.

    Try reloading an updated sound driver for Windows. I believe this may be included in the bootcamp updates on the Apple support site. Otherwise you can search for it based on the type of sound chip used in your MP.
