[pulseaudio-discuss] [PATCH 2/4] alsa-mixer: Add Phantom Jack support

[David Henningsson]

For kernel 3.6, "phantom jack" kctls have been added. They serve as
a marker that a particular port exist. They were made so we can detect
that there actually are speakers and internal mic on a laptop, even if
there are no other indications (volume controls etc).
