Hi all

Forwarding to the AUR list because it seems my reply did not reach the user (Christoph Pegel aka "rio"); jack was marked out-of-date again. Please read below and don't do this for a third time.

Hi

JACK2 is not going to replace JACK1 anytime soon.

There has been at least one discussion regarding this on the Linux Audio User and/or Developer mailing lists, where Paul Davis, one of the primary developers/contributors, discourage distributions to make this transition (eyes were on those that actually did it). I do not recall the topic URI to cite, but anyone curious can get in touch with upstream to verify.

Both branches have functioning APIs - the JACK1 API is tried and tested. JACK2 is an improvement and an alternative for SMP machines, but not a replacement.

However, thanks for the nudge. I have been wanting to add a "jack2" to the repos but never got to it. Expect it in [community].

Regards

rio@eta-ori.net wants to notify you that the following package may be out of date:

   Package Name: jack    Architecture: x86_64    Repository:   Extra    (http://www.archlinux.org/packages/extra/x86_64/jack/)

The user provided the following additional text:

Jack switched to JACK2 series which is currently stable in version 1.9.5 according to http://jackaudio.org/node/29 or even in version 1.9.6 according to http://www.grame.fr/~letz/jackdmp.html

There already is a PKGBUILD for JACK 1.9.6 in the AUR at http://aur.archlinux.org/packages.php?ID=22488

Good that you clarify it for those not so involved. It's a bit unfortunate that jackdmp was renamed to jack2, exactly because it suggests that it's the successor to jack1, which it isn't. They are the two 'biggest' (meaning 'mainstream') implementations of jack that are developed in parallel. Jack1 is the first one, but no other implementation is going to replace it anytime soon, even though debian and derived distros switched to jack2 recently. Each implementation has a couple of benefits and drawbacks, there's currently no 'best' implementation. Jack1 has the benefit that it's well tested, the other implementations don't have any features that make them clearly a better choice.
