The reason for the wrapper script was likely because of the bug where PA was not letting go of the device when jack was asking for it. There was a mechanism for it, but it wasn't working properly. It would only work on some machines, in certain situations. For some, not at all. There was an upstream fix. I haven't had any issues at all since pulseaudio 3.0, and that would indicate that it in deed has been fixed now.

Re: [LAU] So what do you think sucks about Linux audio ?

by cunnilinux himself

to summarize it all. give the users 1) one WORKING ableton clone 2) WORKING VST support & 3) something like WORKING ardour 3 — and they will be happily happy even with linux. even with sloooow and monstrous ubuntu studio. the rest is good to have, but not THAT critical. :))))))))

redirecting vlc output to jack

by Federico Bruni

I've installed vlc-plugin-jack and I'm trying to redirect the output of vlc to jack using this command: $ vlc -p jack --jack-auto-connect VLC media player 2.0.5 Twoflower (revision 2.0.5-0-g1661b7d) JACK audio input (access_jack) --jack-input-auto-connect, --no-jack-input-auto-connect Auto Connection (default disabled) JACK audio output (jack) --jack-auto-connect, --no-jack-auto-connect Automatically connect to writable clients (default enabled) --jack-connect-regex <string> Connect to clients matching Note: add --advanced to your command line to see advanced options. What's wrong? I'm trying to do this because I want to listen to a file (exported by Ardour) while Jack is running. Jack is using the same audio card (internal) as Pulseaudio, that's the source of the problem. Thanks in advance -- Federico

sending sysex while jackd runs

by Brent Busby

Usually when I want to send sysex dumps to midi hardware, I just use the amidi command from the shell, but when QJackCtl is already running (along with lots of other Jack apps), the raw device is already in use by Jack and I can't connect to it at the raw Alsa level anymore. Since it's kind of a pain to have to shut down my whole Jack session just to send a sysex dump, is there an easy way I could just sysex through Jack? Are there any shell commands I should know about that let you do this through Jack Midi rather than Alsa Midi? -- + Brent A.

Now, thanks to the Internet, + Materials Research Ctr + we know this is not true." -Robert Wilensky

Joining LAD and LAU lists (And: more central instances in a "herding-cats" community are good)

by Nils Gey

Hello both lists, I see the reason for a non-discussion announcement list, LAA, but is it really necessary to have twp lists? I know there are several people who only subscribed to one list, but I don't know if this is intentional or not. Why not merge both. The immediate effect would be a stop at the cross posting just to reach the whole community. The mailinglists are from the same service, but I think in the end it would be more convenient and better for everyone to have it all in one place. Yes, I know some of you fear (mostly people in the dev list who do not read LAU) that they will get unwanted mails. But as you can tell from experience topics like "why linux audio sucks", "water as fuel" and other mega/nonsense/offtopic threads get cross posted anyway. And I know some of you think devs and users should be kept seperated. But be honest: Who in the world is subscribed to a linux mailing list and could not stend the occasional developers topic. If you want beginner-level support you most likely don't know how to use lists :) Just to be clear: I am a friend of diversity and seemingly "redundant" applications and projects. There cannot be enough sequencers, samplers, synthesizer, notation programs etc. But when it comes to infrastructure and core building blocks I see no sense in seperation. This is the strong point, compared to other operating/eco-systems. We may friendly compete on a musical or feature basis, but there is no need to border a program just to make it harder for the users to use the program of the "enemy" (from a Windows/OSX POV). In a Linux-Audio world of diversity and individuality, it is good to have central places and instances. We can do whatever we want but unlike the closed source world we have no need to create factions and standards that rival with each other, creating artificial gaps. The most successful of these instances is JACK itself. A centralized audio server, hailed and praised by everyone. And since I am writing this mail already, my personal wish list: Please join the two blog/RSS planets as well (http://www.planet.linuxmusicians.com/, http://linuxaudio.org/planet/ ) Merge Yoshimi and ZynAddSubFx, the JACK versions and experimental forks, the session managers/protocols and a few audio distributions which have not enough manpower and that can be used to boost the other distributions. "Joining/Merging" also can mean for one side to step down honorable and retire the project. Nils http://www.nilsgey.de
