if i start jack bye qjackctl from normal user i receive this errors:

JACK: unable to mlock() port buffers: Cannot allocate memory
cannot use real-time scheduling (FIFO at priority 10) [for thread 
-1236161616, from thread -1236161616] (1: Operation not permitted)
cannot use real-time scheduling (FIFO at priority 20) [for thread 
-1227768912, from thread -1227768912] (1: Operation not permitted

the jack server starts, but then it tell me messages like this "**** 
alsa_pcm: xrun of at least 8.570 msec"


no problem if i run qjackctl from root.

there's something to fix in my configuration?

thank you all.

bye
bobo
