Hi everyone,

I installed Windows 7 RC (build 7100 - 32 Bit version) using bootcamp on my iMac bought in early 2008 (2Gb Ram - 2.67 GHz).

The entire installation went well with no glitch or issues at all and I ran the bootcamp setup in Windows 7 to install the drivers. The problem I'm having is that the sound volume is extremely low in Windows 7. I can barely hear it when I turn the volume up to the max. I don't have volume problems in Leopard - only in Windows 7.

I also tried to install the RealTek Vista driver from my Leopard disk but still the same problem. As anyone run into the same problem? Any suggestions

    You need to download the latest drivers from Realtek. That will solve the problem. Your DVD doesn't have RC compatible drivers.

    How can I find out exactly which sound card model is in my iMac so I download the correct driver?

    Realtek High Definition Audio - choosing Vista, is V &Conn=3&DownTypeID=3

    Press accept, choose driver executable rather than Zip. I chose second download location which came in at 500kbps. First was a dribble at ~70kbps. May be timing, server traffic.

    After install reboot - which removes, you must install reboot again.

    (Same) driver worked for me in Windows 7.

    Works for me only if I go to :

    Version 2.23 posted May 8th.

    I used the exe installer rather than the zipped version this time.

    thanks for the information. Installed driver from May 8th from the RealTek website and now I get sound in Windows 7. The weird thing though is that now I cannot get any sound to come out of my external Bose speakers. It's like Windows 7 doesn't recognize any external speakers with this driver.

    7 is better than Vista but you already went into the control panel Realtek and Sound and made the changes there?

    I've tried everything I could think of using the RealTek Audio Manager. I can't get any sound from my external speakers that work fine in OSX. In Windows 7, the sound only comes out of the built in speakers of the iMac. Could this still be a problem with the driver?
    I'm using the driver

    Has anyone got this to work.
    I have 20" Imac 2008 model.
    Running RC.
    Headphone Jack not recognised.
    When plugging in the headphones/speakers, it detects as Audio Jack/Line IN.

    The sound through internal speakers is very fuzzy when down low and doesnt go very loud.

    I have install realtek drivers. The very latest R226.

    Any leads?

    Hi jason3w, I'm having the exact same problem with the same iMac model, but in Windows XP. I just posted about it here:

    Have you been able to fix this problem? I'm waiting for the newest Realtek drivers to finish downloading from Realtek's website, although judging from this thread maybe I shouldn't hold my breath.

    Are other iMac users having the problem of Windows confusing the headphone jack with the line-in jack?

    I installed the Realtek Vista 228 drivers on my Macbook Pro running Build 7100 of Windows 7 not getting any sound at all.
  • jason3w Level 1 (0 points)
    Just wondering if anyone has figured this one out yet. Very annoying not to have good sound on such a wonderful piece of hardware.
    Thanks in advance

    i want to tell you my problem and my solution.
    i have a late model macbook pro i installed windows7 rtm version x64.
    and i always had windows on my mac (older models) with everthing working properly.

    i did't have sound on my windows7 os. i tried everything form every forum.
    they all had some problems my problem was that windows7 installed the driver by itself. but that my output was only 50% and i heard nothing.
    everybody (including apple) say that you need the realtek/sigmatel driver
    from the apple dvds or from the realtek site.
    and i tried every version of the drivers (i have a lot of old apple cds)
    but still no sound. windows 7 said drivers installed correctly.
    High Definition Sound device or something like thad.

    but now the solution.
    i tried to install windows vista.
    vista said drivers. installed (without apple drivers installed)
    the driver name was:
    Cirrus Logic CS4206a (ab75)

    and these drivers are also on the apple dvds.(
    so i installed windows 7 again.
    and installed this driver first. then started bootcamp. drivers like normally.
    everything now works perfect.

    I fixed mine by installing R2.09 Realtek get a message saying the driver isn't designed for vista but it works without a hitch.

    Good luck
