How to Troubleshoot No Sound on Computer or Audio Playback Issues

Audio ports are exposed to elements that may cause a build-up of dust or even physical damage. Audio performance issues may occur if there is any damage that is caused to the audio cables or the audio ports on the computer.

If you notice that the port or connector has dust or other contaminants, use a can of compressed air to clean the ports.

If you notice physical damage, contact Dell Technical Support to learn more about repair options that are available in your region. If there is no damage, go to the next step.
