if you run

sudo chrt -fp 70 `pidof "jackd"`

as non root without using sudo

chrt -fp 70 `pidof "jackd"`

do you get an error?

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!

Thanks.
