Hi Sergei. Yes this helps a bit. Just now i've tried to run jackd -R [...] as root and it worked :-) But then the normal user can't use jackd und it's surely not a good idea to run jackd as root. I only did this for testing. And now, what should i do? I have the group audio and the normal user is a member of group audio since a long time. But jackd doesn't run in realtime for this user. What's going wrong here?
