I confess that I don't entirely understand this due to inexperience. What 
version MusE & jackd? (Qjackctl is worth installing too).

Will it make any difference to MusE (or indeed Jackd how many inputs your 
audio card has?) - does it not actually work otherwise?

All I understand is that Jackd is part of the audio system, it runs on top of 
ALSA AFAIU - So you'd need to look at your ALSA set-up as well as Jackd.
Audacity is an audio editor, MusE is primarily a MIDI editor. MusE doesn't 
need Jackd to run and probably needs to be compiled specifically to do so.

My answer to most things at the moment is download/get hold of a copy of the 
Agnula / DeMuDi Live CD:

and see how they did it on there.
