I've finally got JACK set up and appears to be working fine. I used these two videos to help.
Anyway, the mixer in Ardour, tuner in rakarrak, etc, all show that there is a signal coming through from my USB microphone. It doesn't look like there is any latency or anything. For some reason though, even though everything is connected to (system: playback 1) and (system playback 2) it still does not produce sound through my speakers or headphones if I plug them in.
Please help, I have been trying to use programs other than audacity for recording my guitar, or even effects in realtime.
