I have a Lenovo Thinkpad T61 with an Intel HDA soundcard.
I'm using Ubuntu Studio 8.04
I followed this guide to get Jack running:
However once I get it running, no applications that have audio actually output anything. For example if I use Audacious with the Jack plugin and play a file, nothing actually happens. If I start up Hydrogen and try to play a drum loop, it's the same thing. I click play, nothing happens. It doesn't even indicate that something is playing, but nothing happens when I click play.
Is there a tutorial on how to use Jack? I'm pretty lost at this point.
