if you run

Why no I don't! And it changes priority. I swore it didn't work
before when I tried it. I've just now added "session required
/lib/security/pam_limits.so" to /etc/pam.d/common-session, as others
suggested, maybe that did something?
So does that mean the -P flag can never set priority 70? I got it from
your site!
Well, if chrt works now without sudo, try running
jackd -R -P 70 -d alsa ...
again. It should work now, too..
Update: I just discovered that running jackd -R -P 70 -dalsa -P -p256 -n2
-r44100 as ROOT doesn't even set priority 70. jackd then runs as a root
process with priority 20, according to both chrt and top.
Apparently my system is not able to run anything higher than 20 priority;
does this mean my kernel is misconfigured, or might it be something else?
