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