  Caitlin BrownAug 14, 2025
  If there's no sound from your Altec Lansing speakers, ensure the AC power cord is plugged into the wall outlet and the power button LED is illuminated. Increase the volume using the volume knob. Check the volume level on your computer's sound card and set it to mid-level. Verify the audio cable is correctly connected to the audio source, specifically the lime green 3.5 mm stereo cable into the 'line-out' or 'audio-out' jack. Test the speakers with another audio source to rule out issues with the original source.

How to fix distorted sound on Altec Lansing Speakers?

  If the sound from your Altec Lansing speakers is distorted, decrease the volume level. Also, adjust the Windows volume and balance controls to the center, then fine-tune using the speaker controller. If you're using .WAV or .MID files, try a different audio source like a music CD, as these files are often of poor quality.

  If your Altec Lansing speakers are producing a crackling sound, check all cable connections to ensure they are properly connected to the 'line-out' or 'audio-out' jack, and not the 'speaker-out' jack. Also, check the Windows volume control and decrease it if it's set too high. Try using an alternate audio source to see if the issue persists.

  If no LEDs are lit on your Altec Lansing speakers, ensure the power is turned on by pressing the Power button on the right satellite. Check that the AC cord is connected to the wall outlet and that the power on LED is illuminated on the right satellite. If you're using a surge suppressor, make sure it's switched on. To confirm the wall outlet is functioning, plug another device into it.

  If you're experiencing a loud hum from your Altec Lansing subwoofer, try unplugging the power cord from the surge protector (if used) and plugging it directly into an AC wall outlet. Also, move your cables and ensure they are making a clear connection. Check the volume on your audio source and lower it if it's set too high.

  If you're experiencing radio interference with your Altec Lansing speakers, it might be because they are too close to a radio tower. Try moving your speakers to see if the interference goes away. You may also consider purchasing a shielded stereo cable from your local electronics store.
