Does Agnula require Jack?????
'Agnula' are the people who created 'Demudi'.
Demudi is a distro, not a program.
Demudi comes with Jack, qjackctrl, and a lot of other music programs, it is prepatched for latency, and in general is setup to be a musicians distro,
BUT, ALSA is what will see the sound device.
The version of ALSA is 1.0.5a and my edirol requires 1.0.7 or better.
Demudi is based on Debian so the standard upgrade path is apt-get, however Debian is very conservative so you can't upgrade past 1.0.6
I have googled till I'm black in the face, if you are not an EXPERT on linux you will not be able to upgrade ALSA,(please somebody tell me Im wrong :-)
The only avenue I can see is find a distro that already has ALSA 1.0.7 or later in it. I've tried Agnula demudi (Debian)
Dyne Bolic 1.3 (Debian)
M-distro (couldn't get it to run)
Dynebolic 1.4.1 is available but being Debian it will probably still be 1.0.5).
http://www.ferventsoftware.com/ (Studio to go) may work however they haven't replied to my email and I'm not paying up front to find it won't run my edirol either.
