Hello guys...I'm running a version of windows 7 on my imac to check it out...i had vista on it previously, and it had sound (with the bootcamp drivers of course). I installed windows 7 on my macbook pro, and the sound worked fine on my laptop. However, I installed windows 7 and all the bootcamp drivers on my imac, and no sound....any ideas as to why this might be? I tried a fresh install....fresh format...everything. I'm clueless as to why it would work on my macbook but not my imac. Thanks for your brainstorming!
