So give it permission :-). Does the user/group that your init.d script
uses to start jack have 'the right stuff' in /etc/security/limits.conf?
cheers.

Jonathan,
it would be very nice if you could also post your comments in normal text
format like all the others. My mail client does not show html formatted mail
by default thus I always have to do additional steps to read your mail.
Thank you
Gerhard

from Ng Oon-Ee:
This identical setup works for me. What versions do you have of
pulse/jack? Please dump jack1 and use jack2 if you want to work with
pulse, there's quite a few fixes (including, coincidentally, one which
fixes module-jack-sink/source in pulseaudio crashing the whole daemon).
Of course, you need a relatively recent pulse (.16 and newer?).
Oh, and I just noticed, please don't run JACK as root either (which is
what /etc/init.d does).
Well, the init.d/jack script I have tries to run it as user 'jeb', which
is my login, which is a member of group 'audio' with appropriate
limits.conf et cetera. jack is running rather nicely as user 'jeb' started
using su from rc.local. But. I am very intrigued with the idea of running
both Pulse and Jack in userland, and I am most astonished to learn that
jack2 should be used with Pulse. So it looks like some good revisions are
in order. Basic question: if I remove both pulseaudio and jack from the
init.d startup set, where and how do they get told to run?
Later, both of you :-)
J.E.B.

Please do not use HTML mail, it's unsightly on my (and probably other's)
machine.

Its not a new idea, its what has always been done. You're doing it with
jack anyway, or your jack apps wouldn't work (jackd as root won't allow
ardour as user to connect for example). Pulseaudio was also written to
function that way.
For pulseaudio (which I'm more familiar with) it gets told to run when
an app requests audio. I think Ubuntu has it in xdg-autostart, and I
believe there's other gnome mechanisms to enable it as well (its a
layered approach). Basically it should 'just work' (tm), as long as
autospawn is enabled in the /etc/pulse/client.conf file.
For jack I don't believe it auto-starts, you have to start it yourself.
I just use a simple script to do that. Most others just use qjackctl,
which normally starts jack up (with that big green triangle).

Does Pulse always start as a daemon, or is it

Pulseaudio runs as a per-user daemon, if run correctly. This is the same
as JACK. It can ALSO be run in 'system-wide' mode but this is not
encouraged by the devs for security and efficiency issues.
The goal is to have Jack always run, to have Pulse be
the default
non-Jack audio API, to have the .asoundrc send user-level ALSA
requests to Pulse.
This is working well in my current system load, except when I restart
Jack; when I restart Jack, the following occurs:
* Pulse goes away as far as any apps are concerned, including
Jack and its own diagnostics;
* the default Gnome volume control (set to point at Pulse
via .asoundrc) spontaneously goes away;
This is symptomatic of a pulseaudio crash.
* If I try /etc/init.d/pulseaudio restart, it
says it is not
started;
Please DO NOT use /etc/init.d/pulseaudio, this points to system-wide
pulse. Start pulseaudio with a simple pulseaudio from the terminal or
the like (perhaps from the F2 prompt).
* if I try ps aux | grep pulse , it says that it
is started.
Most distros have pulse set to autostart, so it would restart itself (as
per-user) after crashing if someone tries to access audio.
In my previous load (AVLinux), all I had to do was
start jackd
in /etc/rc.local, tell Pulse to use Jack as its sink, and tell Pulse
to daemonize via its own .conf file, and it did very well. I have
tried several methods, including setting Jack and Pulse at different
runlevels, but when I try to use Jack as an /etc/init.d item the boot
jack log says that I don't have permission to use realtime scheduling,
and it doesn't run.
