122                 *
123                 * Used to retrieve the sample rate of the JACK audio output
124                 * device. Even though the sample rate of the JACK server might
125                 * change during runtime, the JACK API currently however does not
126                 * allow clients to change the sample rate. So this parameter is
127                 * read only.
128                 *
129                 * This base parameter class has just been overridden for this JACK
130                 * driver to implement a valid default value for sample rate. The
131                 * default value will simply return the sample rate of the currently
132                 * running JACK server. It will return "nothing" if the JACK server
133                 * is not running at that point.
