2.7.0-dev snapshot and JackOSX

[Oliver Oli-3]

Hi Kai,

the snapshot doesn't play well with jack. Ecasound eats all evailable
CPU time and prints a lot of

JackActivationCount::Signal value = 0 ref = 4

messages to the console.

I tested it with

/ecasound -i:jack -o:jack

An older ecasound v2.5.2 does work normally.

I've started writing a reply to you on this a couple of times already, but
then got stuck at the first sentence, as I honestly have no clue what
could be happening. :P

There has been no changes to JACK support between 2.5.2 and the latest 2.7
snapshot (aside client port naming), and JACK support works fine on my
system (although with jack1, not the new jack 1.9.x that you are using on
OS X).

But, but, there are quite a few changes to the core engine code (after
2.6.0), so regressions are possible. But unless I can reproduce the
problem on my local setup, finding the cause will be quite challenging.
Probably the best place to start is for me to try the latest git/snasphot
with jack 1.9.x and see how that works. I'll report back once I've done
that...

sorry about the delay - I still haven't had time to take a look at this.:(
I've been somewhat swamped with work in my daytime job recently, but that
is now looking a bit better again.

I really should solve this (and couple of major items in current
snapshots) as soon as possible, as ~3 weeks from now, it's going to be 10
years since the first public Ecasound release, and it'd be nice to make a
new release to celebrate the milestone... ;)

could you test again with the latest jack2 SVN? There were similar errors
reported on jack-devel:

"Muse and JackActivationCount errors"
http://article.gmane.org/gmane.comp.audio.jackit/19344

I'm not 100% sure if this is the same problem, but at least the error
messages looke the same. Anyways, in case of Muse, the error has
disappeared with latest SVN of JACK2, so retrying the test maybe worth
a try.

I tried to reproduce the problem myself today, with JACK2/SVN (r3570), but
couldn't trigger the case (this on Linux though). There could still be
something wrong (regression since 2.5.2) that shows up only on Mac OS X,
but hopefully this is not the case...
