    Dell Optiplex GX Sound

    I have a Dell Optiplex GX which I got used. After scratching my head wondering why there wasn't any sound, I poked my head into the computer & found that there wasn't any speaker. There was, however, a port that looked like this on the motherboard:

    .
    . EXT
    . SPKR
    .

    Four little wires sticking up, labelled EXT SPKR. So I went and got a speaker, then made the unpleasant discovery that the connector looked like this:

    ___
    |oo|

    Two connectors, not four! However, they were spaced the same as the ones on the circuit board. I fiddled around, but couldn't get the sound to work no matter how hard I tried.

    I have since surmised that the connector on the motherboard is an "analog audio" connector similar to that on the back of a CD player. If this is the case, then the connectors should be arranged like this:

    . . . .
    R GND L

    Anyone have any ideas on how to connect the speaker?

    Just attach the left speaker to L and GND (=ground) and the right one to R and GND.

    Sometimes Alsamixer mutes the sound and /or sets the controls at minimum. Did you check this?

    I only have one speaker, which I want to put into the computer.

    Yes, I did check for muting; my sound automatically mutes sometimes, I don't know why. However, this is not the problem.

    Problem solved--it was a different kind of speaker that I needed.
