CS50/CS55 Troubleshooting: Distortion/Echo

Article ID:

The call audio is distorted/echoing. What can I do?
If you hear distortion or an echo on your call, try the following:
  • First, try reducing the speaking volume. If the issue persists, try reducing the listening volume as well. Click here for instructions.
  • Ensure that the microphone is pointing towards your chin.
  • Listening volume may be too high on the phone. If your phone has a handset volume control, lower this until the distortion disappears.
  • The base may be too close to the computer or phone. Try moving the base 6" away from the phone and 12" away from the computer.
  • Perform a system reset.
If the issue persists, contact our Technical Assistance Center.
