Thank you for your reply. With Rezound I get maybe a couple of xruns 
(and much more clicking) but in general the clicking doesn't cause any 
xrun reports from jack (using other audio software, i.e. muse, ardour 
and csound give no xruns at all but I get the clicking simultaneous with 
graphic activity).

I'll try recompiling the kernel with the latency tracing options and 
I'll let you know the results.

cheers,
