you might try configuring JACK differently.  I also use linux
(although I have yet to get chuck-jack to compile correctly) and have
found that JACK can be rather finnicky about the settings you use.  If
you are not, I would suggest using Qjackctl to configure all of the
options.  It allows much easier control of all the different settings
that simply using the command line.  There are several tutorials
around for minimising xruns .
