This problem is nn a new 15" Macbook Pro 2008 Uni-body.
The sound used to work in Vista but now it doesn't. There's a red light emanating from the headphone jack so I looked up a bunch of threads on it which told me it was the optical audio being toggled to "on". The sound card seems to work fine (all drivers installed) while checking the settings in Vista. Even the tests seem to play something but no sound is coming from the internal speakers. When I plug in headphones, there is no sound coming from them either. I have uninstalled the sound card and had vista reinstall it on restart but to no avail.
I'm guessing the optical audio is permanently on now? I have had no luck with finding threads on disabling the optical audio in vista. Jiggling the headphone plug in the jack didn't work either. Just for clarification, the sound works just great in OSX and no red light problems there.
Anyone have any idea? Thanks for reading!
