[linux-audio-user] RT and Jack problems

Konichiwa!! This has been bothering me for some time. I cannot, for the life of me, run the muse sequencer with full real time (RT) capabilities. I use Slackware 10.2 and a 2.6.15.6 kernel that has RT capabilities compiled in. I start qjackctl which, in turn, starts the jack daemon (jackd) with RT enabled, which is indicated in qjackctl GUI (letters RT showing!!). But, then when I fire up muse I get this: Trying RTC timer... got timer = 14 showMarker 0 tickValues(0x41d3a21) not found(1) tickValues(0x41d3a21) not found(1) 3set realtime scheduler: Operation not permitted watchdog process 22391 _NOT_ running SCHED_FIFO JACK ERROR: cannot lock down memory for RT thread (Cannot allocate memory) JACK ERROR: cannot use real-time scheduling (FIFO at priority 9) [for thread -1284142160, from thread -1284142160] (1: Operation not permitted) error set_schedparam 2:: Operation not permitted set realtime scheduler: Operation not permitted midi thread 22391 _NOT_ running SCHED_FIFO JACK thread not running SCHED_FIFO, try to set... set realtime scheduler: Operation not permitted JACK still not running FIFO !?! ======reliable RT operation not possible!!====== I tried setting the permissions on the /dev/rtc device so that regular users can have access, it didn't help. What could be the issue here, I probably misconfigured or am missing something. Please help. Hiram -- http://www.egoboobits.net/HiramAbiff
