Hopefully you don't need to do anything :-)

You should be able to run SCHED_FIFO as a normal user, no need to login
as root for that. Depending on which kernel you are booting there is a
module that enables access to that that should be automatically loaded,
or it is built into the kernel but needs a tweaked PAM that is part of
the Planet CCRMA packages.
