Introduction
If your Dell XPS 13 7390 is producing distorted audio, crackling sounds, or no sound at all, you may have a failing speaker module that needs to be replaced.
The left and right speakers route audio through small drivers that can wear out over time, especially after long periods of high volume use or exposure to dust and debris. If you notice buzzing, rattling, or uneven sound output, it’s a strong sign the speakers are no longer functioning correctly.
Avoid applying excessive pressure to the speakers during removal, as the drivers and cabling are delicate and can be damaged easily.
Before you begin this repair, power off the laptop completely and disconnect any external devices.
