was able to manually add nodes but only volume controls working

[jwddsinc]

I wasnt able to get the plugin to discover the sonos netowork but after some playing around i was able to add nodes via custom parameters. I can see them now in my admin panel and when i click on a node it correctly displays its state such as "status" "volume" etc. I can set the volume base and treble as well as mute and unmute, however none of the other buttons are working like play pause stop previous next or party mode. Only mute and unmute work. There is no error message when i click them. 

 

Any ideas on what i am doing wrong?

 

Thanks
