It is not possible to use ANY kernel with NO latencies. EVERY kernel
has latencies. The question is how low do you want the latencies to
be? If you can exist with 50mS or higher you might get away with a
standard kernel. If you want to run with 1.2mS latency then you will
absolutely have to have a real-time enabled kernel.

xruns are just an indication of the system not meeting the latency
requirement you set in Jack, i.e. - a by product of how you answered
the question in the first paragraph.
