So a few weeks ago I installed bootcamp on my iMac 27" i7, the latest iMac out yet. When I installed Windows XP professional SP2, (later I let Windows Update do it's thing and let it install SP3 etc). I installed the bootcamp drivers that came with the snow leopard CD's. Sound worked for about 5 minutes, then it didn't so I restarted my iMac and reinstalled the drivers again, then the sound happened to be working again, this time for the whole period. However my INTERNAL mic is not working, I have tried everything for it, installing new drivers, from realtek, reinstalling the drivers that I got from the CD's, I got nothing. This is how my Sounds and Audio Devices Drivers go in properties, Sound playback - Cirrus Logic HD Audio (I also have an option of ATI HD Audio rear back, but that doesn't work in my case) Sound Recording - Cirrus Logic HD Audio ( I have no other options in this one) Just to clarify: I am running Windows XP professional SP3 on the latest iMac with Snow Leopard. Anyone help? Thanks. Edit: I found this from another site http://forum.notebookreview.com/apple-mac-os-x/284363-internal-microphone-not-working-bootcamp.html I cannot do this either.
