hello!
i installed gentoo as my new desktop and audio working system.
but at the moment, i don't get the rlimits with pam rumming.
jackd always tells in its start log:
cannot use real-time scheduling (FIFO at priority 99) [for thread
-1226171488, from thread -1226171488] (1: Operation not permitted)
what did i do:
fist i installed the pro-audio overlay with layman, like described on
the pro-audio site.
then i merged pam from this overlay:
$ emerge -pv pam
These are the packages that would be merged, in order:

Portage overlays:
[1] /usr/portage/local/layman/pro-audio
$
the next step was to make the etc-update, wich added the lines for the
limits on the audio group:
$ cat /etc/security/limits.conf | grep audio
# REALTIME support for audio group users
@audio - rtprio 90
@audio - nice -10
@audio - memlock 250000
$
then i did a relogin, with my user, which is in the audio group:
$ groups
lp wheel audio cdrom video portage z421 vdr
$
and tried to start jack:

my kernel is the actual gentoo-sources:

but there is that problem that the realtime-scheduling gets an operation
not permitted error.
where could the mistake be, did i forget something to configure?
