Hello, I'm new here. Please let me know if I'm posting this in the wrong place.
In short, I can't get any sound out of my system using JACK, and I'm completely stumped.
When I run jack_simple_client, I see sensible-looking console output (see below) and it starts a JACK server (verified with ps). But I don't hear any output.
I've tried other ways of sending sound to JACK (eg jack-play tone.wav or aplay -D plug:jack tone.wav) and the commands complete without error -- but also without making any sound!
I've made sure that PulseAudio isn't running. Beyond that, I'm stumped.
Any suggestions for what to try next would be very welcome!
Thanks.
