+ * @input:
+ * This method is called from the UI when the user selects a previously unselected device.
+ * - Firstly it queries the stream from the device.
+ * - 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
+ * from when we attempt to change profile we will know exactly what device to highlight on that stream.
+ * - 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.

+ 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
