Hello All! I am just starting to use JACK and trying to run some of the example clients. I am able to hear audio from the metronome example by connecting the metronome output to the system playback ports. However, when I connect metronome output to the simple_client input, I do not hear any audio output. Since the simple client copies data from the output port to the input port, I notice that the it should work in the same fashion. Would anyone have any suggestions as to what could be possibly wrong? I am using qjackctl to launch the jack server and view the connections between the different readable clients and the connections seem to show up fine. Thanks for your help. Happy New Year!
