I have a work around for this. I run jack in promiscuous mode as the rd
user and keep the rd daemons running as root (I found to not run them as
root breaks the RN macro).

I have this working for a client using centos 7 with Fred’s repo. I had to
rebuild the jack rpm to the latest version to get promiscuous support. I
also had to rebuild pulseaudio to include jack support so I could use
linphone on the same setup.

In then have a systemd script which starts jack as the user.
