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.
 * GvcMixerStream can represent both a sink or source.
 * Using static card port introspection implies that we know beforehand what
 * outputs and inputs are available to the user.
 * 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.

 * actually provide an alternative.
 *
 * It does this by the following.
 *  - It ignores off profiles.
 *  - It takes the canonical name of the profile. That name is what you get when you
 *    ignore the other direction.
 *  - In the first iteration, it only adds the names of canonical profiles - i e
 *    when the other side is turned off.
 *  - Normally the first iteration covers all cases, but sometimes (e g bluetooth)
 *    it doesn't, so add other profiles whose canonical name isn't already added

  <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.
