RED LIGHT IN HEADPHONE JACK? What does that mean?
I observed a red light actually flashing in the headphone jack of my MacBook. The speakers do not function now, although they functioned until recently. The headphone jack functions, but there was a red light in there. Does anyone know what it means?
