I have a MacBook Pro (17-inch, Mid 2010 MacBookPro6,1 ) that the audio stopped working on.
The audio jack has a red light on in it. In Sys Pref, under Sound, in the Output tab, only Optical digital-out port is listed.
I have reset the PRAM and Reinstalled the OS. Why? Because when the mac is restarted, I can hear the start-up chime. So I know the audio does in fact work. Alternatively, I can plug up some headphones to the jack and it works fine. I have read where you can try to keep plugging a headphone jack into the cable in hopes of hitting the "switch" inside; did it for an hour. No luck.
Anyone have any suggestions before I buy a replacement logic board off eBay and replace it?
I love having a 17-inch MBP and do not want to downgrade to a new 15.
