New 13 MBP no headphone w/bootcamp and W7

No matter what I try to do, I can get sound out of my headphones when booted in Windows 7. Everything works fine in OSX. Apple can't help and Microsoft can't help. No flags in Windows device manager.

I have Bootcamp 3.1 and the Cirrus driver is 6.6001.1.23. I know others have had this problem. Has anyone got a fix?

Thanks in advance.

MBP 13 2010, Mac OS X (10.6.3), Bootcamp and Windows 7

According to this article http://support.apple.com/kb/HT4177 that update seems to be only avaiable through the 'Apple Software Update' in Windows.

Apple has released a Driver update for the MBP 13" to be found here http://support.apple.com/downloads/

As per the release notes it should adress headphone problems on the MBP.

Hope it helps

ok, but what about if you don't have headphone audio with W7 x64 on a regular macbook? doesn't seem that his update would/should work with that.

i had to install what i thought was the most current driver, CS4206 AB99, and i get speaker and microphone working...just not through headphones.

anyone find a universal solution to this?
