An optical jack is a fiber optic connection for the transfer of digital sound via light pulses. To help you with the Logitech issue then we'll need a model number. You can also got to Logitech and pull down a install manual, load driver and such. Most speakers connect with a mini plug or plugs are you sure you're not missing that extra wire connection?
My rig's sound is run off the optical to a high end external DAC into my pre-amp and then a power amp to speakers.....
