- Check your speaker and headphone connections for loose cables or the wrong jack.
- Check your power and volume levels, and try turning all the volume controls up.
- Some speakers have their own volume controls, and you might have to check them all.
- Try connecting using a different USB port.
(And remember that your speakers probably won't work when headphones are plugged in)
NOTE: Before performing any significant repairs, back up your computer's hard drive.
