I recently bought a new Inspiron 620 MT with Logitech speakers. When I went to plug them in, I noticed there were two different speaker jacks. It appears to have a left speaker jack and a right speaker jack. The speakers I bought only have one plug, so I used to right jack., The sound comes out fine. I tried plugging my old Cambridge speakers in to the other jack, but no sound comes out of them. If I switch speakers so that the Cambridge speakers are in the right, Logitech the left, sound comes out of the Cambridge, but not teh Logitech. I there a way I can use both sets of speakers?
The back of the tower should have onboard audio jacks below the blue VGA port. They are pink microphone, green audio out, blue line in. I do not know if the blue line in can be retasked to audio out. Check the Conexant HD audio software installed on your PC.
