Windows 7 beta 1: sound does not work on Macbook Pro (RealTek HD Audio)

This post is googlebait: I couldn't find the solution for this on google, so here's how I solved it. Hopefully others will be spared the messing around.

After installing windows 7 beta 1 (7000) on my macbook pro, and installing the bootcamp drivers off the Leopard Disc, as well as The vista 2.1 bootcamp update, everything worked very nicely... Except sound.

Win7 detected "High Definition Audio Device" and everything looked like it should have worked, but no sound came out of the speakers.

After much mucking around, here's what I did:

Go into the leopard drivers folder. There should be a directory called Drivers, and under that is a file called RealTekSetup.exe. If you try run this normally, it will fail.

What I did next was:

  • Right click it, and select Troubleshoot Compatibility
  • Click Next and wait for it to finish 'Detecting Issues'
  • Select The program Worked in earlier versions of windows...
  • Select Windows Vista
  • Click Next a few times, let the Realtek installer run, reboot, and Presto!
  • As for win7 itself? Well, the beta is faster, nicer, and all around better than vista. I'll never go back. They didn't do a good enough job of copying the dock... but it's still miles ahead of vista, and that's another blog post.
    Byebye!

    Thanks for this, worked for me too :)

    I too, am fairly impressed with 7.. seems as though MS might have learnt their lesson..

    Thanks so much for posting this. Definitely worked as Google-bait!

    I had sound problems on my (mid-2008) MacBook, too, and read about updating the RealTek drivers, but nowhere could I find such a clear explanation of how to do that!

    I'm also impressed with Windows 7, although it's hard un-learning some of the quirks of the Apple keyboard. Even as a very satisfied Mac user, I'm very happy to see Microsoft get its act together with Win7.

    just adding my name to the list of thank you's. I have a late-2007 MacBook Pro and I just installed Windows 7 Beta 1 (32-bit) and I was having the same problem. supposedly sound was coming out but I couldn't hear anything and the red-light was coming out from earphone jack. your solution worked

    Worked like a charm. Thank you so much!

    (Minor point of clarification: the folder you're looking for is on the Leopard Install DVD. I spent a while trying to figure out where this driver install file was on my HFS+ partition before I figured out it was on the DVD.)

    Works perfectly! Thanks for documenting it :)

    Another "thank you" for the fix - also to Altoclef for pointing out that it was on the disc. I was looking around on the C drive for a while at first.

    So far so good.

    Thanks from me too. The procedure to allow a back level update looks like it might be useful!

    THANK YOU! This absolutely worked to fix my Windows 7 dual boot on a macbook.

    Thanks! This was almost a deal breaker for my machine. I almost went back to vista.

    Can confirm that this worked on on my Macbook Pro (May 2008) C2D 2.4 Ghz and Windows 7 Ultimate x64 RTM - thanks for the heads up...solved a lot of head scrathing :)

    Just installed Windows 7 Pro, had the no-sound problem, followed this tutorial, and made it all better. Thanks!

    I have a Macbook Pro 2009 and this solution does not work for me. Tried the cirrius logistic driver as well. I get sound with that driver but its very low. With the realtek troubleshoot solution I get no sound what so ever.

    Aw, this was a really quality post. In theory I'd like to write like this too – taking time and real effort to make a good article… but what can I say… I procrastinate alot and never seem to get something done.

    hello. I have noticed this fix when search on google. Thanks. I have been following it for a while now. However the problem is we do have sound but the sound is very low compare to when using OS X. Could you try fixing the problem with this realtek driver? I read on google and it says because apple use 3 speakers, unlike using 2 like other manufacturer, to produce third mid range sound. The driver does not enable this 3rd speaker, but i dont know how to customize it :(.
    Plz email me if you have solution to it razor813@hotmail.com
    Thanks
