GNOME ALSA Mixer duplicate label "Input Source"

[giorgos000]

The GUI for ALSA mixer shows two options with the same name ("Input Source"), as a user it is difficult to know what they do (and how they are different).

My sound card info (as shown by alsamixer) is:
Card: HDA Intel
Chip: Analog Devices AD1984
