New Cirrus Logic Sound Drivers for Mid-2010 iMac's released Discussion in ' Windows, Linux & Others on the Mac ' started by byronhinson, Aug 27, 2010. Most Liked Posts. Mar 07, 2016  Nonetheless, you're looking at a Mid-2011 iMac with a Cirrus 4206BCNZ audio controller. The newest 64-bit Windows driver I could find for this can be downloaded here. Give it a try. Has anybody got audio working with EFI Windows? MBP 13' E2011 I tried everything yesterday to get audio working on EFI windows and still didn't get it to work. I have an E2011 as well. What I had to do was burn the.iso to a disk and run bootcamp and allow it to partition the drive. I ran everything through it and sound now works.

Incase the above download link does not work, google “CirrusAudio.10.6.1.zip”. We found another working mirror here.

Extract the right type of Driver (depending on your windows XP/ 7/ 32 bit/ 64bit)

Step3:

This step is only for Windows 7 not Vista. Right Click on exe file of driver. Select Properties> Compatibility > Check run in compatibility as shown below. Select Windows Vista from drop down menu and Click OK

Step 4:

Double click the driver and install.
