We should do something about how realtime privilege is administered. Currently, the upstream Debian package jackd installs a file, giving members of audio group access to tuned "rtprio" and "memlock", at /etc/security/limits.d/audio.conf. Also, access to ffado drivers is done from /lib/udev/rules.d/60-ffado.rules, also giving audio group the right to use a set of ffado supported devices. This all works fine in Debian, since the user is in audio group by default. Not on Ubuntu though, since the group is used for other things.
I would prefer that installing jackd would give the user realtime privilege the same way on any Debian derived system, and since audio group is out of the question, we should look at other alternatives. A couple of ideas: * introduce two new groups and make sure both Debian and Ubuntu introduces them. Name them "jack" and "ffado". * Make jack use rt-kit. (We still need a way for jack to get access to ffado devices though) -- ubuntu-studio-devel mailing list [email protected] Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-studio-devel
