That is mostly good news.  Of course the negative side is that it tends to
suggest that your FA-66 is broken. :-(

I think running Ubuntu Studio would be a good first step because that
distribution comes with things already configured for audio/video production
use.  This includes a "low latency" kernel.

Give Ubuntu Studio a go, as you suggested.  Without seeing the error
messages reported by jack it's impossible to say what the problem might be. 
I suspect it might be at least partly due to the use of the generic kernel
(as opposed to a low latency kernel), but this is nothing more than a guess.

Hopefully Ubuntu Studio will provide a solid starting point and require
fewer adjustments to get it working.
