You can attach as many audio playback devices as you want in Windows. For example, I have three audio devices. i.e, monitor speakers, external speakers, and headphones. Each and every playback device is available to you once they are powered on as well as in the significant state. When you have multiple audio playback devices, Windows does its best to pick the default one. In some cases, the audio drivers will choose the default playback device.

When the default configuration isn't the way you like, you are able to change the default playback device in several different ways.
