Give qjackctl a try. It will give you a visual patch bay where you can hook the app up to the sound card. I suspect that the audio output of your app is not driving the sound card. In a terminal I think you could do some jack command, like jack_lsp, to see what's hooked to what, but QJC is much more useful. Good luck, Mark - Mark
