Hi, until about 2 weeks ago I have had no sound problems with my 17" 2011 Macbook Pro. I use Windows 7 64 Ultimate via Bootcamp.


Suddenly the computer no longer detects if headphones are plugged in or not. I have to manually use the sound device settings to switch between headphones and speakers. This was working fine until fairly recently.


Have applied all the latest updates on both the Mac OS and Windows sides.


Appreciate the help

    Pretty sad that someone asks a question and doesn't even get a response that says they have no idea or anything.

    becaue installing audio drivers yourself is a must, is not spelled out, but 'we' answer this type too many times.


    Install the Cirrus (or RealTek in some cases)


    And yes Windows can be fussy at times.


    I just figure some people fiigure things out on their own too. Reallty. People do. On their own.

    Ok, but what do you do when all of this fails (installing Realtek,  Cirrus or both) and the person is still sitting there with sound coming out of the speakers but not the headphones? Headphones are recognized when plugged in as some kind of "line In" object and recognized when they are unplugged. I have been searching for an answer to this question for 2 weeks now and although some of the solutions are different, the results are the same, the headphones that are good, both sets that have been tried, do not work.

    Roll back to the previous version.

    You did it wrong. Use System Restore and Roll Back.

  • Skyrickk Level 1 (0 points)

    I format and reinstall bootcamp again now,  I let you know ...

    (but I just test headphone on Lion osx and headphone doesn't work, before osx update : they works well so...)

  • Csound1 Level 8 (46,900 points)

    I didn't and don't suggest a reinstall of Windows for this, I am out.

  • Skyrickk Level 1 (0 points)

    Partition is formated so ... I MUST reinstall Windows

    And what do you suggest ?

    Even though this is a resurrected two year old thread I'll jump in.


    Get your Lion installation working correctly before attempting Bootcamp and reinstall of Windows. You said the headphones do not work with Lion. So you have done something wrong with your Lion install or you have a hardware issue.


    After you get Lion and sound working then try Bootcamp Assistant making sure you download and install the Lion Bootcamp Windows Support software.

    Ok, maybe, but how to make sound working with Lion ?

    Ok the SMC / PRAM process works to revover the headphone on OSX Lion, pfiou!

    I try under Windows 7 now & let you know


    FYI :


    Reset the SMC > Resetting the System Management Controller (SMC)


    1. Shut down the computer.

    2. Unplug the computer's power cord.

    3. Wait fifteen seconds.

    4. Attach the computer's power cord.

    5. Wait five seconds, then press the power button to turn on the computer.


    Then the PRAM >  About NVRAM and PRAM


    1. Shut down the computer.

    2. Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.

    3. Turn on the computer.

    4. Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.

    5. Hold the keys down until the computer restarts and you hear the startup sound for the second time.

    6. Release the keys.

    Wow - I'd forgotten all about this. Well I "solved" it by giving in, dumping bootcamp and running Win 7 in Parallels. After 1.5 years I've got to say it's the "best of all worlds" computing experience i've ever had (well since my VIC-20, of course). Seriously though - alt-tabbing between apps and not knowing/caring if they are OS X or Win is great and with the unixeque foundation of OS X I don't get those occasional pangs to install Ubuntu or whatever.


    Completely worth it!
