Holger:

Regarding the ALSA portion of your URL (below):

2.) In /etc/asound.conf (system wide) or ~/.asoundrc we redirect
     ALSA-clients to JACK:

     pcm.!default {
         type plug
         slave.pcm "jack"
     }

     pcm.jack {
         type jack
         playback_ports {
             0 system:playback_1
             1 system:playback_2
         }
         capture_ports {
             0 system:capture_1
             1 system:capture_2
         }
     }


On my system, there is no file in either location.  Also, though the file ends 
in '.conf', it looks like C++
code.

Creating the file "~/.asoundrc" with the above contents, had no effect 
on my system, even after rebooting (though logoff/logon might have been 
enough).

Is it something I need to compile, and put the object file somewhere?

Since there was no file in either location, perhaps it's a difference in 
using Lubuntu (LXDE).

I have all the other 'flavors' of Ubuntu that I can test it on. What 
Linux distribution do you use?
