If there are x PA devices on my MOBO, I want to see x of them in JACK. I am one of the "few" mentioned in one post who have a 12 chan. firewire device as well as the devices on the mobo. I have a tri-amp'd stereo using a variety of JACK apps such as CALFrack and zita-lrx. (hopefully quad-amp'd and surround in the future) When I installed UBStudio 12.04 I was glad to see that PA just created the sink/sources in JACK and I didn't have to go figure something out. It's quite nice to be able to patch things around from the PA devices. I have yet to configure a surround sound system and have not seen anything showing up labeled as front, side rear, etc. (Is there a surround sound app? Do any of the apps that will play a dvd or bluray on a PC provide surround? Haven't attempted it yet, just askin.) Also, if you set the default to stereo, how does it choose whether to use the jack (as in 3.5mm) on the front or the rear of the computer case? Regards, Mac

[a bit OT] freesound.org - a short venting

by Julien Claassen

Hello everyone! I hope, that there is someone here, who has strong ties to freesound.org. I went back there today to give registration another go. I said, that their registration was rather a nuiance (captcha codes). Now I find audio captchas, as provided by google. Which is all very well. I can download the audio captcha and listen to it. After a quarter ofan hour Imanaged to guess a right code and then was asked to copy a lot of text into another entry field. OK, even that is no problem. But then, there is no button to press. Javascript. So I think, I might give it a go and send a message to kindly ask for support. But of course: I am politely asked to use the captcha. I have been wondering: for a free site, sharing material with all the world, if the world so desires, they are very well hidden. I know a fair number of commercial web sites, which are easier to access and register with, including - but not limited to - amazon and jpc, a large German musical instruments' shop,... I know, they have problems with spam, but so have others. So have/had we at some time, so have some forums, I once registered with and still, they all weren't that bricked off. - I am part of a minority, even a rather small one, seeing, that I use text-based programs, whereever possible. But I nkow of others, who do have their scripts disabled for various reasons (blind or not). I do hope, that someone here really is part of the team, otherwise I would have wasted words and flooded this list with unnecessary spam of my own. :-) Warm regards Julien ---------------------------------------- http://juliencoder.de/nama/music.html

It was fixed in the upstream code recently. Do you have an >> example of where packaging has broken PA jack interoperability? >> > > https://bugs.launchpad.net/ubuntu/+source/jack-audio-connection-kit/+bug/48… That bug is related to the wrapper script that used to be a part of the qjackctl package, and though it still is for current releases, it hasn't been doing any suspending of PA for quite a while, because the wrapper script has been broken. 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
