Very Low Sound Volume in Windows 7 - Bootcamp on 20" iMac from early 2008

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

Realtek High Definition Audio - choosing Vista, is V 6.0.1.5845

http://www.realtek.com.tw/downloads/downloadsCheck.aspx?Langid=1&PFid=24&Level=4 &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 :

http://www.realtek.com.tw/downloads/

Version 2.23 posted May 8th.

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

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

try going in to the audio setting and setting headphones as the default audio device

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?
Cheers

Hi jason3w, I'm having the exact same problem with the same iMac model, but in Windows XP. I just posted about it here: http://discussions.apple.com/thread.jspa?messageID=9788632

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.

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
Jason

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.
installed.
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.(cirrus.zip)
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 drivers..you get a message saying the driver isn't designed for vista but it works without a hitch.

Good luck

Hey xxfstopxx.
Is that on your imac?
How did you get hold of the older version?
