Well, it is not a stable system. Would not that be reason enough? (doing
it is simple, we just need an epoch of "1"... :-) I don't see how the
packager would be able to say that it works fine.
Unfortunately, I know approximately jack about jack, so I dunno what's busted
or not where. I know packaging-wise, its not hard to roll back, its the
convincing the maintainer to do so part that could take some doing, esp.
given...
One problem is that some software needs post 0.107.0 to even compile!
So
downgrading is a real problem. Dammed if you do, dammed if you don't.
...that 0.106.99 doesn't build locally for me, and as you said, other software
requires post-0.107.0. :\
I have been using current svn and it is much better than 0.109.x,
but
some people have been having problems (thus the post).
I've got a reasonably recent local svn build of 0.112.0, svn r2721 installed
here to poke at for now.
Actually, the only "stable" jack right now is jackmp, a
newer
implementation of the same API, written in C++. That one is good. If
your Jack graph has parallelism, jackmp will execute what it can in
different threads so that load will be spread amongst cores in a multi
cpu system - something which does not happen in the normal jack. I have
had experimental packages for Planet CCRMA for a while (that I have not
yet released). Some (not properly written) software was having problems
with it, but I think a patch was posted recently for one (the last?) of
them, amSynth. So maybe it would be possible to release that for Planet
CCRMA.
Can jackmp be installed in parallel with jack, or would you just package it as
jackmp w/Obsoletes: jack? (i.e., could this potentially get into the fedora
tree, or would it need to reside outside of it)

The problem is not unique to faado. Any use of jack is affected.
Gotcha. Didn't know it was that widespread. I'm quite the novice in the whole
audio area, really only getting involved to try to get things more functional
with the new firewire driver and library stack.
