This will print the tmpdir JACK is using...
$ jackd -V

There are lots of things that can cause xruns.
For starters, make sure you're specifying the --realtime (-R) option
and running `jackstart' rather than `jackd'. This is required for
using capabilities as a normal user (modprobe realtime allcaps=1).
IIRC, Thac's packages may require a command named `jackd-realtime',
instead. Someone will correct me if that is wrong.
