The speaker volumes will be added when I trace their path through the wolfson. It'll currently control handset, wired headset and bluetooth volumes. You currently need to tell it which to control as I have not found any dbus signals to tell what alsa state you are currently in. The displayed vaolumes may be wrong if you start the volume control before the alsa state change. One you use a control to set its volume it will reflect the state of the underlying hardware.<br>
