How to Troubleshoot Audio or Sound Playback Issues

Audio performance issues may occur if there is any type of damage caused to the audio cables or the audio ports on the PC. You may experience symptoms like audio playback stops working, works intermittently, choppy or distorted audio, static noise, etc.

Audio ports are exposed to elements that may cause a build-up of dust or even physical damages. 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 do notice a physical damage, contact Dell Technical Support to learn more about repair options that are available in your region. If there is no damage, proceed to the next step.

A simple reboot can resolve many issues almost immediately. Restarting your PC is an effective way to clear the memory (RAM) and ensure that any errant processes and services that started is shut down.

Restarting your PC closes all the applications or software running on your PC, applications running on the taskbar and dozens of other services that may be running in the background which were started by various applications.
