Cirrus Logic CS4206A (AB 11) in 15" macbook pro i7 on Vista x64 not working

I solved this on my laptop just now, but not quite sure how.

I uninstalled the driver, and clicked the checkbox when uninstalling the driver to delete the files.

Then, after rebooting, it worked. I suspect it worked because I had earlier installed other drivers, which it then defaulted to. I installed the realtek audio drivers off the Mac OS X cd, but I suspect that wasn't it.

I installed cirrus logic drivers from here:
http://www.cirrus.com/en/support/lic/lic3.html?uri=/en/pubs/software/CS4207WinVista_Win7_32-64-bit6-6001-1-21.zip

Or maybe it was the vista drivers I got from:
http://www.stuffedcow.net/macbook_audio

Or maybe these two sources drivers' are the same - and I did just get it from the cirrus site 🙂

If you get it working, I recommend you reply here and state exactly what it was that got it working for you. Just make sure to uninstall the driver and in doing so delete the files too (there's a checkbox in vista). This way it will default to what appears to be older drivers if/when you install those.

Well, I'm really not sure what I did and what it was that got it working. To try and help you solve the problem, here is a screenshot of my drivers information so that you can compare and will know if you're running the same as me. As to where to find the ones I have, I do not know. Another option is perhaps windows vista found them for me. Note that mine say "AB 13", while your subject line says "AB 11".

Vista 32 bit, but I don't know that that would be relevant.

That may be, but it doesn't mean that the driver I have found doesn't have an appropriate 64bit version that will work as well.

Have you tried uninstalling (and deleting) the drivers so that upon reboot windows doesn't install any cirrus driver - and then go into device manager, update driver, and let vista search the net? Perhaps that will find the driver you need.

I would also, after deleting the drivers, recommend you install the realtek drivers off the mac os x cd.

Im having this same problem and havent found a way to fix it yet.

A little extra help would be appreciated!

Having exactly the same problems and cannot seem to find any solution. I've tried deleting and reinstalling the drivers over and over without success.

Very frustrating indeed!

okie,I solved this finally
1)Download the driver from the sound chip official website
2)uninstall the driver which come from MAC OS X DVD and install the latest one you downloaded from sound chip official website
3)Update your windows vista 64 via Windows Update,
4)Install Vista SP1 & SP2

I'm using Vista x86 (32Bit) and I've tried all combinations and drivers found on the internet to no avail.

Vista is now at SP2 (updated automatically via Windows update) and I really do not understand why I'd have to uninstall everything just for a sound driver?!

side3net, when you mention "chip official website" I'm guessing you mean Cirrus' website?

Any help is very much appreciated.

Yes, I mean Cirrus' website

I am using Windows Vista Ultimate 64BIT, so I don't have any information about x86 32BIT version but still have advise for you, try to install the SP1/SP2 not via on Windows update, just download a standalone SP1/SP2 installer and install them manually.

Hi Tennoku,
Thanks for your sharing your idea.
I have tried using your idea to install into my Mac for Vista but it doesn't work.
But I tried using XP Cirrus Logic CS4206A (AB13) its work.
I still want to say thank you for giving your idea and I tried to modify using XP Cirrus Logic CS4206A (AB13) it work in the end. As I have tried many idea but still not works. But in the end I tried use XP Cirrus Logic CS4206A (AB13.
Thanks for your sharing.
