I was wondering if anyone here had an answer to this. I have a new aluminum imac and currently use the internal speakers. I just bought an lcd with a vga input on it. I would like to know if it is possible to disable the sensor on the headphone port, so i could get sound from both the internal speakers and the headphone port. I will have an audio cable running from the computer to the tv, so i would like sound to come out of both. Is this possible? I don't really want to unplug and plug back in the cable every time i want sound out of the tv. thanks.
