Let’s assume that you want to use headphone for Microsoft Edge’s YouTube video but a speaker when watching movies on the VLC media player or Windows Media Player. Such things are not possible on a Windows PC. While Windows 10 v1803 lets you set preferred speakers for an app, Windows 8.1/7 users have no such option. If your version of Windows does not allow you to set different speaker for different apps, you may want to check out Audio Router.
