Hello! this is my first post on these forums and I hope you guys can help me with this issue as I haven't seen any threads on this elsewhere online. My macbook speakers are not working and I can't control the volume as with the optical out headphones issue that a lot of Macbooks seem to have.When I have the headphones in it works fine. When I pull the headphones out however, the red optical light is not on. I tried taking the headphones out and putting them in again and sometimes the optical light comes on and sometimes it doesn't, so I try the fix to wiggle the headphone cord a little, and the light will go off, but the internal speakers still do not work. Please help!
