I had a similar problem before - I think it happened after my machine 
had been powered off without shutting down (not my fault!)

I solved the problem by deleting a pair of temporary jack files 
somewhere, and then rebooting.

I think they are jack buffer files. Try to do a 'locate fifo'.

I'll have a look for them in the morning and post back.
