Jukebox mode not working

[popeen]

From popeen/Booksonic-App#47

I'm trying to get the jukebox mode working for using the phone as remote control for the server.
If I switch to the Jukebox when playing a track it does not play anything on the server and the slider >jumps between 0 and 4 seconds.
The jukebox mode via browser works fine, server plays sound and skipping tracks is possible too.

EDIT: I think it must be a server side issue, a different subsonic android client has the same problem too. >Can you move the issue to the other repository?
