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.

Yeah that red eye is your S/PDIF digital out. Does it stay lid or is it only when you're booting? I'm on W7 right now and I don't have that red eye on.

If you're on the cirrus audio like my 2009 2.66 mbp 15'', then you'll have to use a usb mic to get the mic going on things like ventrilo. The builtin works for the windows sound recorder unless you turned it off in the control panel > sounds property window.

As a contributing member of these forums I find that I am obligated to share my resolution to this issue in the case that people are still having the issue or will refer to these forums in the future. Thanks very much, but after looking through a dozen of similar threads that were of no help I hope that this does not dissapoint.

I simply updated to the latest version of Bootcamp, currently version 2.2, which specifically offers a patch for this issue.

If you have Bootcamp 3.0. The Snow-leopard setup. You won't easily get past this issue with the 2.X update.

However, there is another easy solution for the Headphone Jack and audio issue in Windows. As long as you are using a 32-bit setup. I think this solution isn't tested to work in the 64-bit ones.

I do have Snow Leopard! Jeez will somebody read the information in the link. It says released in late a few weeks ago. I don't care if we're on version 68.3, it's new and it solved the problem for me and I, again, am using Snow Leopard.

This happens on my Macbook Pro as well, I find that if I have headphones plugged in when I boot into Windows 7 it will use the analog signal and not the optical signal.

Solved!!

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.
