If someone can point me to the commit that fixes this, I'm happy to include it in Pd-extended 0.43. I just never use Jack, so I don't know what's what. Things work in my basic tests.
I know that Miller changed this stuff in pure-data.git.

Tx Ivica and Esteban, as similarly afflicted user encouraged by this thread I followed this recommendation, replaced pd and pd-extended with pd-l2ork. Works flawlessly together with jack 1.9.9-test5 from kx-studio ppa, dsp is switchable, some other bugs are gone, my patches run :D You made my day and now I'm going to learn more about L2ork. Gerhard

With 1.9.8 and pd-l2ork all your problems will be solved except for the one caused by jack which in your case should not be a problem unless you physically disconnect (accidentally our otherwise) your audio hardware while jack is running.

HUm... Ok... I will try!
But what the better? Jack 1.9.8 or 1.9.9?

That is the regression I spoke of in pd 0.43 branch. Try pd-l2ork... On Nov 23, 2012 9:27 PM, "Esteban Viveros" <emviveros@gmail.com <mailto:emviveros@gmail.com>> wrote: Ops...

You can switch to a new backend using jack_control (sending some Dbus messages to jackd) without re-starting jackd. No CPU hogging here. - I'm running jack2 - aka 1.9.9.4 from git. robin -- Esteban Viveros (27) 8815 7170 (27) 3066 0359 (11) 95761 4125 (11) 2738 7868 www.bandpage.com/estebanviveros <http://soundcloud.com/estebanviveros> https://www.facebook.com/estebanviveros.art http://www.papodecompositor-es.blogspot.com.br/ http://expurgacao.art.br/ -- Esteban Viveros (27) 8815 7170 (27) 3066 0359 (11) 95761 4125 (11) 2738 7868 www.bandpage.com/estebanviveros <http://soundcloud.com/estebanviveros> https://www.facebook.com/estebanviveros.art http://www.papodecompositor-es.blogspot.com.br/ http://expurgacao.art.br/ _______________________________________________ Pd-list@iem.at <mailto:Pd-list@iem.at> mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list-- Esteban Viveros
