libgnome-volume-control is a copy library that's supposed to be used as
a git sub-module. If your project uses some of libgnome-volume-control's
strings in a user-facing manner, don't forget to add those files to your
POTFILES.in for translation.

* This method attempts to match a sink or source with its relevant UI device.

* But that does not mean that all of these inputs and outputs are available to be used.
* For instance we might be able to see that there is a HDMI port available but if
* we are on the default analog stereo output profile there is no valid sink for
* that HDMI device. We first need to change profile and when update_sink() is called
* only then can we match the new hdmi sink with its corresponding device.
*
* Firstly it checks to see if the incoming stream has no ports.
* - If a stream has no ports and no valid card id, it goes ahead and makes a new
* device (software/network devices are only detectable at the sink/source level)
* If the stream has ports it will match each port against the stream using match_stream_with_devices().
*
* This method should always find a match.

In PulseAudio without ucm, ports will show up with the following names:
Headphones - analog-output-headphones
Headset mic - analog-input-headset-mic (was: analog-input-microphone-headset)
Jack in mic-in mode - analog-input-headphone-mic (was: analog-input-microphone)
However, since regular mics also show up as analog-input-microphone,
we need to check for certain controls on alsa mixer level too, to know
if we deal with a separate mic jack, or a multi-function jack with a
mic-in mode (also called "headphone mic").
We check for the following names:
Headphone Mic Jack - indicates headphone and mic-in mode share the same jack,
i e, not two separate jacks. Hardware cannot distinguish between a
headphone and a mic.
Headset Mic Phantom Jack - indicates headset jack where hardware can not
distinguish between headphones and headsets
Headset Mic Jack - indicates headset jack where hardware can distinguish
between headphones and headsets. There is no use popping up a dialog in
this case, unless we already need to do this for the mic-in mode.
From the PA_PROCOTOL_VERSION=34, The device_port structure adds 2 members
availability_group and type, with the help of these 2 members, we could
consolidate the port checking and port setting for non-ucm and with-ucm
cases.

<description>
This library contains code to access PulseAudio using a GObject
based library, shared between gnome-control-center, gnome-settings-daemon
and gnome-shell. It is not API stable, and it is meant to be used
as a submodule.
