Hallo,

Well, not it's grandchildren, at least not in my tests. If I put only
/usr/bin/jackd in /etc/set_rtlimits.conf, then start "set_rtlimits -r
/usr/bin/jackd -R -d alsa -d hw:0", jackd runs with higher priority.
However if I then start ardour, it complains about not being able to
gain RT scheduling. 

The fix for me is, to also add /usr/bin/ardour to
/etc/set_rtlimits.conf, and then start ardour as: "set_rtlimits -r
/usr/bin/ardour" after jackd. 

Ciao
