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.
Which audio driver is used by MacBook Pro 7.1??? I'm running BootCamp (Windows7 Ultimate x64) and I'm having a problem with audio input,.
Thanks for the reply! Here is my Hardware Id: HDAUDIO FUNC01&VEN8384&DEV7680&SUBSYS106B1A00&REV1034 HDAUDIO FUNC01&VEN8384&DEV7680&SUBSYS106B1A00 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. Thanks for the help!
