    To everybody if your having trouble with sound. (low or no sound at all)
    everybody is talking about going to the website of realtek. (with very poor internet connection)
    or use the drivers on your mac disc. (used to work for me with my macbook in the past)
    i had this problem,
    windows 7 said, drivers installed correctly. High definition sound device. or something like that.
    but i have no sound. and this has nothing to do with the red led light from your headphone jack.
    i had this problem running Mac osx 10.5.7 & snow leopard. windows 7.xxx/7600
    but here is how i solved this one
    i installed vista and vista immediately installed de CIRRUS sound driver. also located on your mac disc.
    so no HIGH DEFINITION SOUND DEVICE for me
    i installed windows 7x64 inserted my mac disc (bootcamp 2.0) and installed the CIRRUS driver
    now windows 7 says:
    Cirrus Logic cs4206a (ab75) driver installed.
    now i have sound. not a 100% but around 80/90% and i can live with it.

    my only problem now is i heard you can't turn your keyboard backlit off.
    because off windows 7 ambient light sensor Bllsht
    hope this helps.

    Boot Camp => format the "BOOTCAMP" partition (so as to make it NTFS) = Automatic Update for the video card and then to realtek.com/downloads and sure enought, following along the "High Definition Audio Codecs (Software)" link, got me to Windows 7 drivers (just make sure to browse, then "let me pick" and point to where you unzipped the above downloaded driver); but alas, device could not start.

    Restarted my MacBook Pro and a Windows security alert popped up for a couple Realtek pieces of software (e.g. SkyTel), but still nothing; then clicked on the Sound icon by the time, Windows offered me to Apply Fix, so I did, but still nothing (besides the driver now reverting back to Microsoft!).

    Went back and re-installed drivers (manually, letting me pick, and browsing to location) and picked the second driver (there were like 7 drivers offered, but all seemingly the same): no avail; so, picked the next and so on and so forth, until all were tried and none helped.

    I like the suggestion though (just wondering what the right driver is)...

    Nice clue! Was hoping it was only that some have Realtek and some have SigmaTel (I tried the former to no avail, so hopeful of the latter).

    Went to download.com and searched for "sigmatel high definition audio" and downloaded the codecs (albeit from Dell), ran the installer and nothing. Noticed the audio drivers were still from Microsoft (i.e. not sure what the Dell installer did), so tried updating the driver using the folder the codec above unpacked to, restarted, but still didn't help.

    Will continue to look...

    Another good suggestion, but didn't help me.

    cirrus.com/en/support/drivers and then picked Windows 2000 in the Generic Audio Driver drop down menu (albeit not Win7, was the highest OS to pick from), then used the CS4630 version (again, just going with the highest version offered), updated drivers to that, restarted, but no better.

    I think I'm going to go back to Realtek or SigmaTel and get my OS 10.5 DVD (as opposed to thinking a quick download).

    I wish I could take back my third post: I think most MacBooks (or Pro) have either the Realtek or the Sigmatel; i.e. and not Cirrus Logic.

    Anyway, finally got my OS 10.5 DVD and put it in (while booted to Windows 7) and ran the setup.exe/bootcamp and just clicked continue anyway for "may not be compatible" and let it install everything (and there was also another "may not" for the intel chipset), and then restarted, and BAM! I have sound!

    LESSON: I believe the instructions probably state to run your Mac OS DVD in Windows (a.k.a. the bootcamp program for windows, not to be confused with the Mac version to setup a partition and restart your computer to your Windows DVD); just follow instructions and don't try to manually just grab the right Audio drivers (or the other few that aren't built-in to the Windows installer).

    RobNYC2009's solution worked on a black intel macbook that came with tiger. I was wondering what that led was for. I was thinking it was for making it easier to spot the record jack.

    Please excuse a really stupid question I'm running only windows on my macbook pro because of prior problems when I tried to run both os's. Like others on this thread, after upgrading to win7 I have no audio. None of the other suggestions on the thread have worked, so I want to try running the mac bootcamp .exe while in win7 (I hope this is what that post meant). If I run the os x 10.5.7 bootcamp .exe while in win 7 as suggested to get my audio to work, will I lose the applications & other stuff I currently have on my macbook? I am truly desperate at this point.

    I've followed all the advice on here and still only have my sound half working on windows 7. Sound is still very low (coming from built in speakers), and the red light is still on at the headphone jack.

    I also just dicovered headsets do not work properly when plugged in (no microphone sound is picked up on the headset mic).

    Has anyone had any luck with this?

    Please help!!

    I would like this issue to be addressed. I've tried everything in this thread (except the Vista install - because I'm not buying ANOTHER OS for troubleshooting purposes). None of it worked.

    i had the same situation with my macbook black.
    i tried manytimes uninstalling and reinstalling the audio driver using the files on my macbook DVD... but doesn't work.

    so I tried to download the new version of the driver... it says compatible with windows 7 and finally it works! my soundcard is Realtek... here is the link

    ftp://202.134.71.21/pc/audio/VistaWin7R242.zip

    if ur mac uses SigmaTel then perhaps downloading the new SigmaTel driver will solve the problem...
    cheers
