I know this thread belongs in Win7 forum, but I'm posting it here because mac users have experience with these windows sound problems on Macs.
I installed Win7 with boot camp and everything works fine except sound. Windows is telling me that I have my drivers updated, but sound isn't working at all. OS itself is producing the sound (it appears so), but it isn't sending it to my Macbook Pro's speakers. I tried installing quite a few different audio drivers from Intel's website, but none of them fixes the problem. My Macbook Pro is somewhere between 3-4 years old. I don't what is the name of the sound device itself, it doesn't show up neither on Win7 nor on Mac OS X.
Hi there go to Control panel->Device Manager->Sound,Video and game controllers(just click left on it and Properties->Details and search in rolled Hardware Ids(this must match PCI&VEN_10EC&DEV_0269&SUBSYS_10280006&REV_1000(this is only example not your match),or post here hardware ids.
I also noticed one other thing last night. I get red light from audio jack for headphones. I tried turning off the jack with a toothpick, but the light is still there. If I plug in headphones, I get no sound either. The weird thing (and relieving) is that I get no red light when in Mac OS X and sound also works perfectly fine. So it's Win7-only issue.
Tried a few sigmatel drivers, but they don't work. But I did fix it.
The problem was actually that I needed to install Boot Camp on Win7. I feel very stupid now
Well I actually tried that right away from Snow Leopard's DVD, but I didn't find anything windows-based on it, I also didn't know that the drivers I need to install are just combined into Boot Camp for Win.
I always thought of Boot Camp as just an assistant, because I think you can create new partition manually with Disk Utilities, boot from Windows installation DVD, format the new partition to NTFS and continue with installation. But I really had no idea that Apple is also providing drivers through Boot Camp.
