I hope it's this easy, but are you using "jackstart" with qjackctl
(look in "Setup...-->Server Path" in qjackclt)?  I think this is
needed instead of "jackd" for the privelages you want.

And since you're asking for techniques to make it work, I like to
create a group "audio" and then add myself and or other users to that
group (say it ends up being group 501).  Then when you load realcap do
it with:

/sbin/modprobe allcaps=1 gid=501

You can even just edit the init script that Fernando mentions to make
this load this way at boot.

The spot where it says:

REALCAP_OPTS="allcaps=1"

Change to:

REALCAP_OPTS="allcaps=1 gid=501"
