Hi,
I just discovered that pd -jack will start a jackd if there is none running already.
In src/s_audio_jack.c I found a comment saying that
(If no JACK server exists, jack_client_open() will start uone up by
default. It's not clear whether or not this is desirable; see long Pd
list thread started by yvan volochine, June 2013)
I would hereby vote for not starting the jackd server automatically, as jackd would pick up any ~/.jackdrc present in the user's homedir, which might not fit the desired sound card setup as ~/.jackdrc gets rewritten by qjackctl with its most recently used settings.
Once users (such as me) start using multiple sound cards, at multiple sampling rats, with multiple other parameters, it becomes very hard to have Pd autostart jack with the desired settings automatically. It would start jackd, but with possibly confusing and unwanted settings.
I changed the line 340 in src/s_audio_jack.c to jack_client = jack_client_open (client_name, JackNoStartServer, &status, NULL) and recompiled and am happy with the new behavior.
cheers, P
Why not submit a patch for a new startup flag which controls this behavior? That way the souped-up setup gurus don't clash with the the users who "just want sound" with a default jack install. (Thus no need for voting, which is so 19th century anyway...)

Thanks for this advice. I don't think anyone, at least Miller, wants another startup flag. Should have had said 'advocate' more than 'voting', which is so 17th century perhaps.
What's wrong with another startup flag? Aside from the -h output, people who don't need it never see it. -Jonathan

Hi,
in Debian (and derivatives, like Ubuntu), starting with puredata_0.46.6-1, jack autostart has been disabled (see the "fix_dont_autostart_jack.patch" at [1]).
I would hereby vote for not starting the jackd server automatically, as jackd would pick up any ~/.jackdrc present in the user's homedir, which might not fit the desired sound card setup as ~/.jackdrc gets rewritten by qjackctl with its most recently used settings.
but this was not the reason, as i think it's rather simple to work around (just don't automatically pick jack as Pd's audio backend; and make sure that jack is running with the correct setting before you switch audio to "jack")
the reason why i *was* changed is, that once jack has been autostarted, it is impossible to quit Pd properly (most likely due to the fork-off of pd-gui; but i haven't been able to properly track it down).
but anyhow, i agree: i would also vote for disabling jack-autostart, as it makes more trouble than it solves.

Ah, interesting behavior. Well, it seems this one gets ruled out once autostart is disabled.

OK.. I've applied the no-autostart patch (and another I found, about .config files) from the debian patches. Another of them (fix_vararg-on-arm64.patch got applied earlier.
Hoping to get a 0.47 out in Sept.
cheers Miller

sorry, if i was unclear. i was talking about the puredata Debian package, which is *almost* pd-vanilla.
luckily, there are no Debian specific patches in the puredata codebase.

btw, if you are using the Debian packages, you should get something like: $ pd -version Pd-0.46.6 ("Debian-0.46.6-2") $

Ah, and it has a numbering scheme that adds an -N to the version number I understand.

Yes, I guess this is good.

Nice! I stick to my own compiled ones, but it sure is great that Debian packages exist!
