I've re-found this article:

http://en.opensuse.org/JackLab/Assigning_real-time_priorities_with_PAM

- it's for SUSE, maybe you'll be able to figure out how to do the same
for your distro (Debian ?).

PAM (Pluggable Authentication Module) does the job of allowing non-root
user to increase audio priority.
