I'm using an Inspiron 8200 as a cheap audio workstation. I've installed the Debian kernel and xfce as the desktop.
I've compiled a 2.6.18 kernel with the rt patch from http://people.redhat.com/mingo/realt...tch-2.6.18-rt5
using the instructions at http://forums.debian.net/viewtopic.php?t=13123
. I've allowed realtime preemption in menuconfig.
The kernel compiles and installs properly but when I try to run jack in realtime mode, it returns the message
"jackstart: cannot get realtime capabilities, current capabilities are:
probably running under a kernel with capabilities disabled,
a suitable kernel would have printed something like "=eip"
back from read, ret = 1 errno == Success
jackstart: could not give capabilities: Operation not permitted
I've tried editing edit /etc/security/limits.conf, appending @audio - rtprio 99
@audio - nice -10 @audio - memlock 250000 to the end of the file but no better.
Can anyone tell me what I'm doing wrong?
Further, dmesg|grep real returns
