Background

I am trying to fix bug #528050. The problem is that gnome-volume-control needs
to store persistent references to a system's GstMixerTracks. It currently uses
a string key based on the values of the following tuple:

  (GstMixer->device-name, GstMixer->factory->long_name, GstMixerTrack->label)

Actually, it uses the GstMixerTrack's "untranslated-label" property, falling
back to "label" if it is NULL.

The Problem

My new laptop has six problematic GstMixerTracks. The first three have a label
of "Capture", "Capture 1" and "Capture 2", but they all share the same
untranslated label property of "Capture". The next three all have the same
label and untranslated label: "Input Source"

So, my question is: is gnome-volume-control correct to use these properties as
a key to uniquely identify a GstMixerTrack?
