I cloned the WebUI volume control to a Windows desktop application. Because I found myself use airplay on my windows desktop rather than using the WebUI.
I think I would share this little application if anyone else find it useful.
I just tried the volume control…works great. Just a suggestion. if you can add the play, pause, stop with the volume control…this would make this app even better.
You can also try my script to control volumio with multimedia keys of your keyboard (play/pause vol+/vol- next/prev). You can also attach any keyboard shortcut for that. The advantage is that’s running in background (no need to have a focus).
