Answer 1

I found a fix for this problem, so here it is.
what you need
1.mac osx dvd [where all the bootcamp drivers are]
2.7-zip software
goto the mac osx dvd, find the cirrus drivers. it should be inside drivers folder.
extract the files using 7-zip and save them on desktop
now goto device manager, and update the cirrus audio manually, when the option of have disk comes, navigate to the desktop folder where u saved the extracted drivers and select the driver file.
when windows gives a list of which drivers to install choose AB77 .
thats it then u'll be good to go after the new drivers install.
if you cannot find the [AB 77] use a disk from a 2009 macbook pro
