That's possible, but since there is already code in GstMixerTrack to
handle duplicate translated names it seemed logical to apply this
solution to handle untranslated names and also translated/untranslated
names of GstMixerOptions.

I get the feeling the ALSA developers do not consider this a problem;
the alsa-utils such as alsamixer already correctly handle the situation
by displaying the tracks to the user with the names "Capture", "Capture
1", "Capture 2".

Output from 'amixer controls':

        numid=16,iface=MIXER,name='Input Source'
        numid=17,iface=MIXER,name='Input Source',index=1
        numid=18,iface=MIXER,name='Input Source',index=2

But I can always ask. I'd just prefer to not have to wait until 2.6.28
for this laptop to be usable. :(
