Computer sound help

Green plug on PC is the output to the speakers. If they are not amplified there may not be enough wattage in the PC's sound card to make them work. Also check that the audio is not muted (speaker icon by clock has an international no go sign on it). If its not muted, double-click the icon and check that all the different outputs are max'd out and no check marks to mute that particular function. Also, if its a newer (1 year or less) PC, the output jacks on the PC can be set for different functiions. May have to open the mixer program for the sound card and look to be sure that the green jack is actually set as line or speaker out rather than some other function.
