mcdevito75 here, Your computer already has the Audio installed, you just need the speakers themselves hoked up. If your a bit handy simply obseve the cable ends of the cables supplied with the speakers, plug the cables into the speakers, one cable should connect both speakers together for stereo and a 3rd cable should connect 1 speaker with the back of your computer, there will be a symbol for speaker on the back of your computer. Do not force and cables, as they should fit with a gentle push into place on the speakers and computer. Visit your local Radio Shack or Staples for more info.

I recommend you to check the speaker settings.
Follow the steps in the below link to check settings:

Not sure if the TV headphone jack would give you stereo out, but you can try that. If it's 1/4" jack, you'll need a 1/4" to 1/8" adapter.

If that doesn't work, you can use an male RCA Y cable to female 1/8" stereo jack.

You should be able to find both items at your local Radio Shack or possibly Best Buy.

1. first findout the problem is due to speaker or from your computer soun driver or hardware.
2. for checking speaker, connect to an ipod or walkman to the speaker input if it works the speaker is okay
3. check the computer sound driver software may installed properly
4. for these type dxdiag on run in the start menu
5. check the sound driver problem, if it re install the sound driver by using its cd
