That's the optical output. It's an issue in Boot Camp.When I start Boot Camp Windows 7 I get a red light in my head phone jack.Is there anything to fix it?
Why dont my Microphones work in windows?That's the optical output. It's an issue in Boot Camp.
Apple released an update to Boot Camp 2 (Leopard) for XP and Vista last week that fixed it but they are yet to issue the update for Boot Camp 3 (Snow Leopard) to fix this in Windows 7.
Windows 7 is currently not supported in Boot Camp but it seems to work OK on most machines using the drivers from the Snow Leopard disc.
I have a MacBook Pro and I had this same problem after I updated iTunes. I disabled the sound driver and noticed that the red light turned off, so that meant it was a driver problem. So, I tried to re-install the driver, using the automatic driver install from Microsoft, but this never worked.
The solution was to install the Cirrus Logic CS4206A (AB 76) sound driver.
Hope this helps.
I solved this problem in my MBP early 2009 by installing the High Definition Audio Driver from Realtek. Bootcamp Cirrus drivers (I tried several BootCamp versions) would not solve the problem. Initially I could not understand if the problem was hardware or software related. After installing Realtek's driver the red light disappeared and I was able to play audio files in my BootCamp Windows 10 x64 partition. Hope this can help someone else having the same or similar problem.This thread is super old, how did you find it.
Also I already solved this problem , but thanks for posting anyways if anyone else needs to solve the problem
