[linux-audio-user] Why jackd can't get realtime?

When running jackd trying to get realtime I get: $ jackd -R -d alsa (...) cannot use real-time scheduling (FIFO at priority 20) [for thread -1228579920, from thread -1228579920] (1: Operation not permitted) cannot use real-time scheduling (FIFO at priority 10) [for thread -1236972624, from thread -1236972624] (1: Operation not permitted) However I thought everything was set up properly on my Debian sid: $ uname -r 2.6.19.1-rt15 $ grep PREEMPT_RT /boot/config-`uname -r` CONFIG_PREEMPT_RT=3Dy $ dpkg -s libpam-modules | grep Version Version: 0.79-4 $ tail /etc/security/limits.conf # there is no way to say "allow locking all memory", 4G should be enough # * - rt_priority 0 * - nice 0 # @audio - rt_priority 100 @audio - nice -10 @audio - memlock 4000000 # End of file Any ideas welcome.
