I've had this problem for a while now, I just ignored it in the past, now I'm really fed up. I've tried everything, downloading Realteck, burning BootCamp drivers onto the CD (I have a Lion which came with no disc), I tried playing around with the Sound in Control Pannel. Someone please help me!

    you have realtek? you don't even mention the Mac.

     

    and yes we all almost always need to manually download and install and Realtek works if that is what you have. Cirrus Audio is harder to find and is common to notebooks and iMac

    I am having the same problem. I installed windows 7 x64 onto my partitioned hd on a early 2009 imac. I have it up and running but I have no sound. I do not have the Lion DVD so that is out of the question. Any idea how to get the sound drivers up?

    THERE IS NO DVD FOR LION

     

    Why not read. When you are at the forums head click Overview. There you find links to "Support" and "Manuals" and you had to have used Boot Camp Assistant and missed the instructions in there, with the "save to disk or print"

     

    You would have had to save the Windows support software in the Assistant too. That is built into Lion version.

     

    Lion is electronic only. With new Macs having only network install (but good idea to SAVE the installer ESD package - before running the install because on restart it auto-destructs and removes it from the hard drive (why they don't keep a tiny 4GB file locally is probably not going to satisfy or ever seem rational and logical).

     

    You have to use Boot Camp Assistant to get the Apple Support Software for Windows.

    The hatter, when you said "you have realtek? You don't even mention the Mac?" I have, I said I got a Lion. So yeah, what do you sugest I do? It says I got Cirrus Audio.

    Unfortunately it did not work, any other suggestions. I appreciate your help, thank you. Oh for more information, my HDMI says it's not plugged in, it has a red arrow pointing down.

    i found the solution!!! =) before install windows on osx lion update your version of bootcamp (check the update manager on osx ), after that proceed with the bootcamp aplication , check that you have 2 options that shows the bootcamp window manager:- install windows 7 and -download addons and drivers ( something like that the important thing and it says literally boot camp gonna download drivers for your mac to  make windows work properly) press  and check the two options after that the manager gonna burn a cd or dvd with all the download package of drivers ;after that the windows installation begins; minutes later you have windows working in bootcamp and you  can think its done but THERES NO SOUND or other things maybe like isight not working or etc ; take the burned cd or dvd and make it run  on your actual windows with no sound system , then a windows appear saying it gonna install all the drivers needed for finishing the bootcamp install click yes or accept  after installing your mac gonna restart and  FINALLy  you have windows working on a mac 100%  with sound =)

    I have a MacBook Pro and I had this same problem after I updated iTunes. I disabled the sound driver and noticed that the red light turned off, so that meant it was  a driver problem. So, I tried to re-install the driver, using the automatic driver install from Microsoft, but this never worked.

    The solution was to install the Cirrus Logic CS4206A (AB 76) sound driver.

    Hope this helps.
