Audacity Forum

* i've also sent a mail to the audacity-user mailinglist about this issue!


I asked it before but many linux users have an JAck issue with Audacity. We're wondering why the jack connections aren't constant available, so also when Audacity isn't playing. This is very annoying when you want to use Audacity with other apps for example.

Check this discussion please: http://linuxmusicians.com/viewtopic.php?f=28&t=552

thanks in advance

If you find anything out, please post. I've yet to see Audacity working satisfactorily with JACK, and it would be such a boon if it did.

I hope this issue is clear > Audacity only makes connections with system: playback1 and playback2 if you play a song. But when you hit the stop button the connections are lost....

I have the same problem when recording. I have to start recording then press pause while I make the connections, as the input connections are not visible until Audacity is in record mode.

Ok, this seems to be a important problem to fix in Audacity, here is a discussion about it:
http://linuxmusicians.com/viewtopic.php?f=28&t=552
And also on the LAU mailinglist there was a discussion about it a few months ago...

Apps like AlsaPlayer and ReZound does handle this better, so it should be possible to fix in Audacity!!

Where are the devs of Audacity? Would be nice if I got an reaction...

anyway, vote here for the 'feature'
http://audacityteam.org/wiki/index.php? ... hancements
Do not close JACK connections on stop

Basically they spend most of their (spare time) developing this wonderful software for us - so thay don't get much time to visit this board very often. he board is mainly "staffed" by a handful of volunteers also giving up some of their spare time - though one of the developers, Gale Andrews, does occasionally drop by the forum and answers posts and other do from time to time - but mostly you get users helping other users.

But you did exactly the right thing in voting and posting the link to the Wiki - the FR page on the Wiki is one of the places where the developers do hang out. And by the way the Adding Features To Audacity section is used as a feeder to the Wiki- items get discussed there amongst users and hen are later moved to the Pending Feature Requests page in the wiki (I actually do that as one of my tasks) - and from there the developers triage the requests to decide which are doable and which are not.

So do please keep posting grammo, and help to keep this board lively and useful......

It could be that the devs of Audacity have a good reason for this behavior, we didn't think of... so a reaction would be nice...

I don't think that is the case. There have been a problems using Audacity with JACK for as long as I know. There are several issues that contribute to it not being fixed, such as;
JACK is not yet at version 1.0 stable (currently 0.109.2) and developing against software that is alpha/beta is always going to be problematic.
Audacity uses portaudio as its audio I/O library - this is useful as portaudio is portable and cross platform. It seems to me that this is where the problem lies - Portaudio and Jack do not yet work well together.
Audacity developers do not publish builds of Audacity for Linux, they just release the source code and allow each distribution to compile it for their system.

Maybe it would be a good idea if the Audacity developers produces one build of Audacity for a popular Linux platform as a kind of reference build - preferably Ubuntu (because that's what I use ) or perhaps Debian.

I think good JACK support is the first important thing for Linux users! A good linux audio apps should have at least some great jack support!!
You say JAck isn't stable... I think it is.

I don't know how other devs of other apps does it... But mostly they produce just a source code and the specific packages are made by the different distro package builders...
