It can't work if JACK is running anyway because all clients are
required to support the server sample rate.
That I know.
WRT realtime, last i heard was that Gentoo does not supply a new
enough version of PAM (0.80 or higher is required)
that I don't know. Bummer...
# equery which pam
/usr/portage/local/layman/pro-audio/sys-libs/pam/pam-0.78-r6.ebuild
Thanks... back to realtime-lsm
Hi,
pam-0.78-r6 should work. I use this version and jack runs with rt-prio.
Check your /etc/security/limits.conf for the right entries
Well... it's good to know that version should work. I made sure I had
it. The entries are the same.
# REALTIME support for audio group users
@audio - rtprio 100
@audio - nice -10
@audio - memlock 250000
You can also find up to date ebuilds for rt-kernels and audio software
in the pro-audio overlay. There you can set the use of realtime-lsm by
setting a USE variable but I'd suggest to go with pam. More information
can be found in the wiki:

That's what I'm referring to, as I mentioned in my first msg:
I'm following the directions on the wiki for the RT kernel at:
http://proaudio.tuxfamily.org/wiki/index.php?title=Realtime_%28RT%29_Kernel
ulimit -l replies
# ulimit -l
250000
So, as Marc-Olivier mentioned, at least that is being read. But, is
there anything else that I can check?
With my latest kernel compile and with the change to the alsamixer to
44.1k (as I mentioned before) running qjackctl
does not say that it can't run realtime, but the "RT" symbol is not
lighted ("Realtime" IS checked in the setup)
Here's a log:

So, I'm getting there, but I'm not certain that I'm really running jack
in realtime mode.
