Here's a screen shot of the Sonos App on On Controls. Right now it is kind of limited, but it can only get better. You can change the volume of the Sonos Zone-player or speaker, and change songs int eh queue. Right now you can only add songs to the queue and add playlists from your music library. Although if you do have a queue going with songs added to Rhapsody, or spotify you can change whats playing in the Queue, but the songs already have to be in the queue. If anything, the volume can now be changed in the On Controls App. Let me know if you guys have any questions.
