Symptoms

The audio playback does not work when a Dell monitor is connected to the computer using a DisplayPort or High Definition Media Interface (HDMI).

Cause

When an audio-supported video cable is being used such as a DisplayPort or HDMI cable, Windows may change the default audio playback device to the audio-supported cable assuming that another audio device is being used. The issue may occur when a laptop is coming out of sleep mode as the system is detecting the audio-capable cable first.

Resolution

Change the Playback Device configuration in Control Panel

NOTE: Only one device can be set as a default playback device.

  1. Click Start, and then click Settings (gear icon).
  2. Click System.
  3. On the left menu, click Sound.
  4. Under choose your output device, select the audio device that you want to use.
