Hi list, (Sorry this question has already been discussed but the search function in the archive of the list does not work) Is anyone working on the problem of getting Jack up and running on MacOS again? I installed Jack with brew but I get these “could not handle external client request” errors which seems to be old problems from looking at search results and GitHub discussions - problems introduced when MacOS audio architecture was changed a while back. Is there any progress on these matters? Is someone working on it? I need Jack as it is a dependency to another library I would like to use but I realize that I might have to abandon MacOS as a platform in the process. Kindest regards, Stefan

[Jack-Devel] Linux Distro with Least problems with Jack

by liebrecht＠grossmann-venter.com

I am ditching my windows audio production workstation and need to get the Linux software under my belt. Cant work with the crashorama and closed nature of windows anymore. It bytes always in the end. I therefore have to master Jack asap as it is crucial to the software I will use (Mixbus by Harrison). Questions 1) Please suggest a Linux distro that you have found works best with the current newest Jack release 2) Please give me the best known in-depth tutorial on Jack that will get me up and running. 3) Please suggest the best to your experience visual connection interface application that works with jack, e.g. qjackctl etc etc. Thanks

by BJ Raz

I just got the recent drivers for my audio card from Realtek and when I put then into Jackport Audio I get the following error message: Assertion failed! Program: D:\Users\brazg\AppData\Local\Programs\Jack\jackd.exe File: C:\Users\letz\Desktop\Developpements\portaudio-21-11-2012\src\common\pa_process.c, Line 1558 Expression: framesToProcess != 0 Jack main caught signal 22 For some reason the audio device: *ASIO::Realtek ASIO* does this. ᐧ

[Jack-Devel] Looking for visual "Clipping indicator" (linux command line interface)

by Jaime T

Hi all. Is there software that someone could recommend that would provide a visual indicator of clipping occuring in a jack stream? Extra points if the visual indicator remains set until manually reset. Double extra points if the program can run inside a (linux) command-line environment? If there's nothing out there (yet), I'm going to have to try to add something to jack_meter... TIA, Jaime
