No new sessions while using JACK

Nah, it's not a permission problem. He can write to his disk using alsa. But not with jack and RT.
For me it's either PAM (etc/....audio.conf) or the user not being in the audio group. Or both.
It would be useful to know the distribution also.

But i do see a non consistent approach

It just would be nice to see the distribution, and the details : what does he do exactly ..
