Troubleshooting Steps

 

Most speaker systems have an amplifier inside the speaker. For such a speaker to work correctly they will require an audio source that is not amplified. Depending on the sound card, there will either be solely a line-out jack or both a speaker-out and line-out connector. The difference between the two outputs is that speaker-out is amplified by the sound card. While the line-out, like the audio output on the back of a VCR, requires an amplifier to listen to it.

If your speakers are plugged into the speaker-out jack and your volume is too high or distorted and you have already adjusted the Windows volume control? Plug your speakers into the line-out jack to prevent overdriving the speakers.

It is possible that either the speakers or the sound card has an internal fault. The best way to isolate this type of problem is to use a different audio source than your sound card uses. This lets you test the speakers. You can use a portable CD player, the headphone jack on your CD or DVD drive, or the headphone jack on your VCR, for example.

In some instances, the speakers have been known to pick up noise from an external source. This is difficult to isolate. Every electrical device in your house or office gives off some amount of radio frequency (RF) or electromagnetic interference (EMI) signals. Some of the more common items that can cause noise are:

  • Your monitor
  • Fluorescent lights
  • An uninterruptible power supply (UPS)
  • The computer itself
  • Fans

 

Turn off as many of these devices as possible before you test your speakers. Also, if your speakers are plugged into a power strip or UPS, try plugging them directly into the wall outlet instead.

If you are unsure that the speakers are emitting the noise, please refer to the main troubleshooting article for Abnormal Noise troubleshooting.
