Well, if chrt works now without sudo, try running
jackd -R -P 70 -d alsa ...
again. It should work now, too..
Believe it or not, I thought of that. It doesn't work. I also tried with Csound, no luck. chrt -fp 70 `pidof "jackd"` works, jackd -R -P 70 -dalsa etc doesn't (it starts jackd with all the appropriate options except realtime). Is it possible for realtime not to be compiled into jackd? I have 0.103.0 from Debian testing.
