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

hallo,

i have the same problem. I bought the new iMac 21,5" i3 3,2GHz and would install windows vista 32 bit via bootcamp. Everthing is all right, but the sound isn't. Cirrus Logic CS4206a (ab18) says that is couldn't install. the code is 37. Now can you explain me step by step what I have to do, that it works.
PLEASE it is very urgent!

I've tried everything that was stated previously above and my audio system still doesn't work I have a 13" Macbook Pro running windows vista 32 bit and nothing works
any hepl would be greatly appreciated

First-time Mac user here. Like many, I encountered the issue with no sound in Vista 32-bit after installing with Bootcamp, but somehow managed to fix it using a combination of other suggestions.

The following worked for me:

1) In Device Manager, attempted updating the Cirrus driver with no luck
2) Right clicked, selecting 'Update Driver Software'
3) Clicked 'Browse my Computer for Driver Software'
4) Located the folder of the downloaded driver mentioned on page 1 of this thread ( http://www.cirrus.com/en/products/pro/detail/P1233.html )
5) Clicked 'Next', and waited for the driver to update/install

After this, I was thrilled to have been notified that the installation was successful, and now it appears that sound is working. I have yet to install Service Pack 1 or 2, but I hope that they don't mess anything up. I'll update if anything changes.

An issue I had noticed initially was that when I plugged in earphones or external speakers to the jack, audio would continue to come out the main speakers of the MacBook as well as through the earphones simultaneously. To fix this, I simply:

1) Went to Control Panel
2) Clicked 'Sound'
3) Right clicked 'Headphones' and clicked 'Set as Default Device'

After this, Vista would recognize when I had my earphones plugged in, and when I didn't. The transition between the two isn't always graceful or on the fly (I noticed with YouTube videos that I had to reload the page for the audio to adjust to whichever configuration I was testing).

I'm not sure if it's a foolproof fix, but I'm more than happy to share whatever I can with the community, as it's been surprisingly difficult finding a clear solution to a problem that's apparently so widespread.

Good luck!

Yes !!!!! you are the first one to have stated an answer that worked for me (although the link did not directly work, I searched the Driver from that webpage). I did not uninstall the original driver - I DL'd the driver from cirrus and updated from the download. Fixed ! (for having no sound in 32 bit - Vista on my MBP). Thank you for the info.

Hello, i have found a fix for this. You need to go to this website:

http://www.drivercure.com/driver/driver_vendor.php?id=9262AF0C-2F22-4A6B-8B01-8F A21DFF57CB

Once on this page click "download" where it says download URL. Next you will be prompted to enter a security code, then click download. Choose to save the file to your computer. Now, once the drivers are downloaded, you will need winzip or winrar to unzip the files. After the files are unzipped, go to "Device Manager" on your computer, if you cannot find this, just search it. Next, open up the drop list under "Sound, video, and game contollers". Double click on "Cirrus Logic" and then click on the "Driver" tab at the top, then click on "Update Driver". Next click on "browse computer for driver". Now search for the file that you downloaded and unzipped, then click next. The computer will now begin to install the new drivers and your speakers should start working shortly. Hope this helps if you have not solved this problem yet. By the way, im running Vista x64 on my macbook pro.

Hi all:

I'm running Windows 7 64 bit on a Boot Camp partition on my 15" i7 MacBook Pro.

I was having the same problem many people have been having (reduced sound levels from my sound card- it was actually playing sound properly but in mono) and I was finally able to fix the problem.

Here's how I fixed it.

Step 1: I downloaded the most recent Cirrus Logic drivers from the Cirrus Logic page. The CS4207 driver is actually more appropriately named "CS42**" driver.
--> go to this page: http://www.cirrus.com/en/products/cs4207.html
--> click the "Resources" tab
--> in the "Resources" tab, under the "Tools & Software" heading, select the appropriate driver ZIP file for your particular configuration. Since I am operating in Windows 7 64 bit, I chose the "CS4207 Windows Vista (32/64-bit) and Windows 7 (32/64-bit) Driver, 8/2010, v6.6001.1.26 : 100 KB"
--> download the file to your desktop
--> create a folder on your desktop called CS4207 Drivers (the name doesn't actually matter)
--> move the downloaded ZIP file to this new folder
--> expand the ZIP file within this new folder

Step 2. Go to Control Panel, Device Manager.

Step 3. In Device Manager, open up the "Sound, vide and game controllers" sub menu.

Step 4. If you're like me, you had 4 NVIDIA High Definition Audio entries, and one Cirrus or Intel entry. Click on the Cirrus or Intel entry for the Sound controller. Uninstall the driver and, if it gives you the option to delete the driver files used, do so.

Step 5: Go back to Device Manager, and select "Scan for hardware changes" from the right click dropdown menu.

Step 6. Let your system automatically install whatever driver it wants.

Step 7. Select that new driver entry in Device Manager; right click the entry to update the driver; choose the Browse option, then the Let Me Pick option; and then select the new folder on your desktop as the driver location.

Thats basically all it took for me.

I hope this was helful for someone else- took me 2 days to figure this out.

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

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!
