+ * 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 but has a valid card ID (bluetooth), it will attempt
+ *   to match the device with the stream using the card id.
+ * - 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.
