This is a perplexing one. When I use Sooperlooper with just my computer's internal mic and speakers it works fine. But when I try and use it with my Presonus Audiobox (which I have been able to configure in qjackctl and also record/playback with in Ardour, so no compatibility issues) it doesn't show up in the audio connections window of qjackctl at all. Nothing. Is there some other place I need to configure that audio interface before software applications will recognize it as the audio interface of JACK?
Any help is greatly appreciated.
