Comment 14 for bug 1245495

I know a real patch would help more, but I don't know how to create one yet.

Adding a function to the MediaPlayer class in /src/media-player.vala:

+ public bool has_proxy () {
+ return (this.proxy != null)
+ }

Modifying the add_player function in /src/sound-menu.vala:

 var section = new Menu ();
 section.append_item (player_item);
- section.append_item (playback_item);
+ if (player.has_poxy())
+ section.append_item (playback_item);

From what I see this would require a restart of indicator-sound if the MPRIS gets re-enabled, but no sound items would be displayed if the proxy is absent.
