Got an '07 iMac, and just reinstalled Win7 on it, while playing around with the partition sizes. Before, everything worked fine. Now, I have no sound (though, if I strain my imagination, I think I can hear something). According to Windows, everything's working fine; says the driver is functioning just as it should. I've reset the computer, no dice. I've checked things in OS X, and its just fine. Any thoughts?
