[Jack-Devel] jack2: issues w. 32bit clients in 64bit jackd since Fedora 22

by anders.vinjar＠bek.no

Hi all. After upgrading to fc22 during summer, I'm having issues with 32bit jack clients running in my 64bit jackd. I'd be thankful for any clues to what's going on, and ways to debug this. And if others would care to check, and confirm/disprove the same behavior, please tell me what you get. Here's what happens: The 32bit clients connect well, but the callbacks never seem to return, making jackd send out a steady stream of xruns and errors: JackEngine::XRun: client = simple_client was not finished, state = Triggered I'm checking with jack2 installed (jack-1.9.10), with .i686 and .x86_64 versions installed using the standard fedora packages. The same 32bit clients work well in fc21, fc20, and ubuntu 14.04 (in a vm on the same hardware). Afaik, nothing has changed vs. the -mixed flag in jackd, and would expect 32bit clients to run well inside a 64bit jackd. Checking with example-clients/simple-client.c from the jack sources: $ gcc -m32 -g -O -lm -ljack simple_client.c -o simple_client $ ./simple_client - results in the noted behavior. Without -m32 everything's fine. Thanks, -anders

[Jack-Devel] Status of cgroups support/coexistence?

by Mark Haun

On a Linux 4.2 system with realtime scheduling controlled by cgroups, what is the current recommended strategy to get jackd working as a non-root user? There was an old wiki page, https://github.com/jackaudio/jackaudio.github.com/wiki/Cgroups describing some built-in support (e.g. --with-default-cgroup configuration switch). But none of this is in the current git HEAD. (I am using jack2 1.9.11.) And a somewhat related question: Is there currently support for running jack as root and allowing client programs with multiple UIDs to connect? I tried following an old recipe using JACK_PROMISCUOUS_SERVER, but it didn't seem to make any difference; running jackd as root, only root can connect. Regards, Mark

Not that I consider myself a jack-dev anymore, but how about you just share out your patch on jack-devel or as a pull-request on github? My impression is that somebody is just going to merge it. ;) Cheers -- mail: adi(a)thur.de http://adi.thur.de PGP/GPG: key via keyserver

[Jack-Devel] Want to get involved in testing Windows Jack - Already using Ableton, etc.

by djbarney

Hi Jack people, I am doing a lot of testing of various types of Windows audio software at the moment. ReWire is good but Jack would make a nice alternative. I tested in Windows Vista and got Jack Audio running, but it crashed a few times and I got very crackly audio. After moving to my Windows 7 64bit dual boot installation (I eventually discovered the custom/hacked PAX drivers for my X-Fi card to replace buggy Creative drivers) I found Jack more stable but still get this crackling in the audio - this is not present in any other audio from my system, MME, ASIO, games, ReWire, etc. So how do I get involved with the Windows version ? I can put in bug reports and do testing. I have been known to fire up windows compilers (after eating the right kind of mushrooms, ya know how it is) but I'm not an experienced coder. Frankly I wonder what is causing the crackling because the rest of Jack in Windows seems to be working and stable. DJ Barney -- ~~~ http://djbarney.org

[Jack-Devel] jackd on low memory embedded systems

by Matt Flax

Hi there, I am wanting to run jackd on low resourced/power embedded systems (running Linux). When I run jackd on these systems it tries to lock down way to much memory ... much more then is available. Is the amount of memory locked down by jackd configurable ? Or is it an operating system set thing ? Does anyone have any constructive ideas or suggestions for running jackd on these low resource embedded systems ? thanks Matt
