Troubleshoot Sound on Your Computer

If you think you have a sound card installed, but you still can’t hear any sound on your computer, follow these instructions:

  1. Make sure your speakers are plugged into a working power source and turned on.
  2. Make sure your speakers are correctly connected to the computer. On your speakers, find the cable that plugs into your computer. Make sure that the speaker cable is plugged into the speakers and the correct jack on the computer. For example, if the cable is a 1/8 inch cable, there should be a round jack for it on the back of the computer. If it is a universal serial bus (USB) cable, it will plug into any USB port on your computer.
  3. Make sure that the speaker volume is not muted or turned down too low. Open Volume Control by clicking the Start button, clicking Control Panel, clicking Hardware and Sound, and then, under Audio Devices and Sound, clicking Adjust system volume. Under Main Volume, move the slider up or down to raise or lower the volume.  Note: Some mobile PCs have an external volume control on the outside of the case. If you’re using a mobile PC, check the external volume control.
  4. Make sure your headphones are not plugged into the line out (headphone) jack of your sound card or computer (unless you want to be listening with headphones rather than speakers). When you plug in headphones, most computers automatically cut the sound to the speakers.
  5. If these steps don’t solve the problem, contact Lan Pros for assistance.
