Audio on windows 7 64 bit Macbook Air.

Hello everyone.

I've had a look through the posts relating to audio on windows and I don't think my issue matches any of them.

Ok so my problem is this, I installed a legit version of win7 pro 64 bit on my i7 macbook air. I've done it a few times before on different computers with no problems. I created the usb with the bootcamp 4.0 drivers in osx 10.7.

Everything was going great for about 2 weeks. Then one day out of no where the audio stops. I think it may have been when I plugged the laptop into my work cinema display and the audio routes through the screen, but not sure.

Now I am left with no audio in windows.

I generally pretty good at fixing windows but this has got me stumped. I have uninstalled the drivers and tried installing realteck drivers, tried the same with cirrus audio drivers, then I tried to uninstall bootcamp drivers and re install those!!

From here unless anyone can suggest anything I will have to reinstall which I really don't want to do. I have everything set up just right and it took ages.

Thanks in advance for any suggestions.

nevermind I formatted and it seems to be fixed.
