Please change the volume from Terminal and observe the speaker icon's
lack of updates.  It should update at least when the Frame is shown:

http://git.sugarlabs.org/projects/sugar/repos/mainline/blobs/master/extensions/deviceicon/speaker.py#line51

I doubt this is the only code that depends on expose events being
fired.  Unfortunately, the lack of an expose event is a hard problem
to solve.
