[QUOTE="hughvane, post: 1386496, member: 56231"] Are you trying to go direct from the audio port to speakers, or via an amplifier? From what you describe concerning external working, but internal not, and your message about the red light, I'd also suggest the audio port has a stuck cancel switch (cuts out the internal spkrs when an audio jack is inserted). How to fix? Various methods, but the toothpick or dummy audio jack repeatedly inserted/removed (volume turned right down) [I]may[/I] fix the problem, but you might eventually need to open up the Macbook and to get at the audio port to clean and free the stuck switch.
