Setting up Audio
Dell laptops and tablets have built‑in speakers that support 2‑channel audio.
To use the built‑in speakers, play the media and set the volume to your
desired level.
Dell computers and tablets also support a 3.5 mm audio port to allow you to
connect external speakers. If you are setting up 2‑channel audio, connect
the speakers to the 3.5 mm headphone port or the audio port.
Dell desktops may support 5.1/7.1 audio. If you are setting up 5.1/7.1 audio,
you must connect the speakers to the appropriate ports for best audio
output.
NOTE: For more information on the ports available on your computer
