If like me, you work on the computer and often use a headset to make calls, but in between calls you don’t want to wear the headset but it would be great to listen to music. The problem is, you start up Spotify and play your playlist and the sound is still coming through the headset. It doesn’t have to though. There is a way to tell Windows 10 which sound device to use for which application.
With the application running, right click on the sound icon in the system tray and select Open Sound Settings.
