If pulseaudio expects the strings to be from small set, should we have
defines for them?

If pulseaudio can't understand short versions, do these need fixing,

hda_auto_parser.c:		"Internal Mic", "Dock Mic", "Mic", "Rear Mic", "Front Mic"
hda_auto_parser.c:			return "Headset Mic";
hda_auto_parser.c:			return "Headphone Mic";
hda_auto_parser.c:			return "Mic";
hda_auto_parser.c:		return "Headphone Mic";
hda_jack.c:						    cfg, "Headphone Mic");
hda_jack.c:						    cfg, "Headphone Mic");
hda_proc.c:		"Line In", "Aux", "Mic", "Telephony",
