Introduction

The Dell Latitude E7470 laptop's internal speaker units are responsible for audio output and are paired for stereo sound. If one or both units fail, sound output is compromised. Signs of a failing speaker include decreased volume, distortion, or garbled sound. The left and right speakers are hardwired together and sold as a single unit.
