  - It assumes that if the stream is null that it cannot be a bluetooth or network stream (they never show unless they have valid sinks and sources)
  In the scenario of a NULL stream on the device
       - It fetches the device's preferred profile or if NUll the profile with the highest priority on that device.
       - It then caches this device in control->priv->cached_desired_input_id so that when the update_source triggered

       - It attempts to swap the profile on the card from that device and returns.
- Next, it handles network or bluetooth streams that only require their stream to be made the default.
- Next it deals with port changes so if the stream's active port is not the same as the port on the device
  it will attempt to change the port on that stream to be same as the device. If this fails it will return.
- Finally it will set this new stream to be the default stream and emit a signal for the UI confirming the active input device.</doc>

       - It attempts to swap the profile on the card from that device and returns.
- Next, it handles network or bluetooth streams that only require their stream to be made the default.
- Next it deals with port changes so if the stream's active port is not the same as the port on the device
  it will attempt to change the port on that stream to be same as the device. If this fails it will return.
- Finally it will set this new stream to be the default stream and emit a signal for the UI confirming the active output device.</doc>

 - device->priv->profiles (profiles to be added to combobox)
 - device->priv->supported_profiles (all profiles of this port)
 - device->priv->disable_profile_swapping (whether to show the combobox)

This method attempts to reduce the list of profiles visible to the user by figuring out
from the context of that device (whether it's an input or an output) what profiles
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
   in a second iteration.</doc>
