thanks
No. I still use kernel 2.6.7 with Ingo realtime-preempt patch (my video card,
a nvidia card, don't work well with mm kernel series, required by newer
patchs) and realtime-lsm module for capabilities. JACK version 0.99.13. ALSA
1.0.7. If you need I can try a new version of kernel...
I use jack with --enable-posix-shm and --with-default-tmpdir=/mnt/jack, so I
add the following lines in my fstab:
tmpfs /mnt/jack tmpfs defaults 0 0
ramfs /dev/shm ramfs defaults 0 0
My buffer size is 128, with a latency of 5.33ms. My jack command line
(qjackctl):
/usr/bin/jackstart -R -dalsa -dhw:0 -r48000 -p128 -n2

Shouldn't need to use jackstart if using realtime-lsm. Just run jackd as

You don't have realtime permissions. Are you sure you've got the
realtime LSM loaded? How is it configured?

$ /usr/bin/jackstart -R -dalsa -dhw:0 -r48000 -p128 -n2
For this to work you either have linux-2.4 with the "capabilities"
patch installed, or are running linux-2.6 with an older version of
realtime-lsm with its `allcaps' option selected. If the latter, try
setting any=1 or gid=<yourgroupnumber> instead.
