Hi I had realtime working just fine (debian/etch, 2.6.18-rt8), but now it doesn't. And i can't figure out why... When I start qjackctl I get this in messages: cannot use real-time scheduling (FIFO at priority 10) [for thread -1210070368, from thread -1210070368] (1: Operation not permitted) atte@ajstrup:~$ grep -v '#' /etc/security/limits.conf @audio - rtprio 99 @audio - memlock 500000 @audio - nice -10 atte@ajstrup:~$ grep atte /etc/group dialout:x:20:atte,emil,britt cdrom:x:24:atte,emil,britt floppy:x:25:atte,emil,britt audio:x:29:atte,emil,britt video:x:44:atte,emil,britt plugdev:x:46:atte,emil,britt atte:x:1000: atte@ajstrup:~$ sudo apt-get install libpam0g Reading package lists...
