[Jackaudio] Trying to debug jackd crash (version 2)

by Ethan Funk

Howdy jack-audio people. It's good to have the list back! I have been developing a collection of programs that work together for radio automation. It's a port of a project I wrote and use currently under OSX to run a radio station I own. At this point, I have all the core stuff working on Ubuntu, less a new UI, which I have not written yet. But that is mostly OK because my old OSX UI can control most of the functions in the new components, and will work as I transition things. So that bring me to the mostly working part. I have been testing an testing and testing, and have come across a problem where my programs cause jackd to crash after running as a system for a few days. The core-mixer program is persistent. Media players are forked by, and connect back to the core-mixer (arServer) to play their files, etc., as needed, then quit. It appears this repeated life cycle of the media players are the cause, because the jackd crash always occurs just after a media player disconnects from jackd. I am running Ubuntu Studio tools, so as soon as jackd quits, it is re-run. Crashes again one to two more times, then runs without further disturbance, except that my core-mixer it written to quits when it get notice that jackd shutdown. All my core code is in straight C and can be found at https://github.com/eafunk/audiorack. Jackd does not crash with the core-mixer running with a single audio source connected to it, with out the media players loading and unloading. Neither does it quick when left alone with an audio source hard-routed to a destination without the core-mixer running. Can any one suggest how I could debug jackd to figure out what my program is doing to cause the crash? Debugging my code is pointless here, because it doesn't crashes when jackd does. Any pointers on how I can build jackd (the dbus multi-processor version) for debugging? Build tools give me nightmares, but I have to dig in to get this sorted out. Thanks Ethan Funk

[Jackaudio] Processing callback thread safety guarantees

by Danny Wensley

Hi all, I'm in the process of building a small application that utilises Jack in order to interface with audio hardware. Specifically, although this detail is only partially relevant, I'm writing it in Rust (using some community FFI bindings). I was wondering what the thread safety guarantees of calling the processing callback are. Specifically, I was wondering if it can be guaranteed that the callback will only be called on a single thread at any given time? This is primarily because it determines whether or not it is required for the callback to be marked as "Sync" in Rust - which would indicate that the callback's data must be thread safe, a restriction I'd prefer to avoid. Thanks in advance.

[Jackaudio] OSX Catalina build

by Alexander.Carot＠hs-anhalt.de

Hello all, I just tried to run JACK2 on OSX Catalina. I installed the binary and it sais that it is not supported for Catalina anymore. The first try of compiling it on my machine failed. I couldn’t spend much time investigating the current problem but it obviously deals with the 32-Bit build. Can anyone send me a pointer how to possibly quickly resolve the build issue ? Thanks in advance, best Alex Alexander Carôt -- Prof. Dr.-Ing.

[Jackaudio] Get raw pcm from jack port

by Louis Foster

I've been trying to find a good way to a stream of audio from jack into opusenc (the official opus encoder tool) and then pass it to something like oggfwd to send to Icecast. However, a few different things I've tried in python haven't worked out, and I'm trying to not have to rely on an "audio file player" (like sox or pyaudio) to sit in the middle. Now I'm wondering if there's a way I can get the raw pcm data from jack. Is this possible? Is there an existing tool?

[Jackaudio] A macOS Jack Dream

by Colin Sullivan

Greetings all, Below is a message I sent some time ago to the somewhat inactive jackosx mailing list. Now sharing it here. I seek your comments, advice, and any relevant insights around future possibilities of Jack on the macOS platform. ------ Colin > Greetings list, > > I’m curious to start a discussion about the future of Jack on macOS and to share my dream. > > I’d like to steer clear of what has been expressed numerous times in several forums (though please correct me if I am wrong). Just to recap where we are at: > > 1. JackPilot still works on macOS 10.14 as a way to easily install Jack, start Jack, set options and make connections. > 2. The “JackRouter” as a core audio device feature does not work - this means that you cannot route iTunes or any arbitrary application through Jack on macOS. Jack can only be used with applications that can select their own audio interface, such as Ableton Live, Reaper, SuperCollider, etc. I’ll call these “advanced audio” apps below. > > I am a software developer and electronic music maker. I rely on the JackPilot application heavily for #1 above. > > My dream is that macOS users can continue to have an easy way to install and run Jack, to route audio between advanced audio apps. > > I would be interested to contribute efforts towards making #1 happen. I don’t care to maintain #2, though it would be nice, it is quite an effort (and ongoing) and I don’t use it. > > My questions to you as a member of this mailing list: > > 1. Do you think there is enough interest in an easy way to install and use Jack on macOS without the core audio device feature? > > 2. My sense is the JackPilot application is no longer maintained. Does it make sense to continue to have a macOS specific installer & GUI application? Should we just somehow repackage qjackctl to run on macOS properly? > > 3. Imagine a scenario where JackPilot no longer runs on updated Macs. Would this impact you? I can compile jack2 and use it from the command-line, but this is not fun for folks who are starting to experiment with computer music and want to try routing things. > > Please forgive me if there are similar threads and many thanks for reading! > ------ > Colin >

[Jackaudio] Starting a synthesiser.....

by Robert

Dear All, Just a quick question. How popular is JACK these days? If I write a JACK synthesiser, will I be able to use it with some other software? For example, will I be able to use my synthesiser with sequencer program? Do you know any good sequencers? With kind regards, Robert

[Jackaudio] Disconnection Problems between Linux&Windows

by Stefan Rinass

Hi, i hope this is the right place regarding my question.. I have problems with a Netjack connection between two Machines whenever, as it seems, a certain amount of channels are being added and i cannot figure out the cause. Machine 1 runs Ubuntu Eean and Ardour 5 on a I3-3210 with 4 GB RAM and a huge swap (just to avoid running out of memory) Machine 2 runs W7 on a i5-4570, 8GB of RAM with Jack Netdriver (1.9.11) and a rather old Version of FL Studio, using Jack Netrouter as audio Device, unsing onboard Audio Jack Netdriver on the Windows side is so configured that it offers 2 capture channels and 32 Playback channels in Async mode. Jack on the Server side (Ubuntu) runs in RT (also tried non-RT) 2048/2, 44.1 KHz Link between both is 1 GBit/sec. Afaik bow cards are idenitified as RTL8169. First problem: - transferring more than two audio channels simultaneously usually leds into "stutter" on Ardour. Second Problem: -transferring Audio over more than 10 Channels kills JackD immediate on the server side. Log is on the end of this mail. Done an iperf(3) between both machines shows no sign of Packet loss (TCP and UDP), Transfer speed is about 903 GBit/sec. Ping is between 0.2 and 0.3 msec Tried with different MTU´s on both sides between 1500 and 9000, before i replaced my old Slave machine with the I3 it sometimes helped to switch between 1500-900-1500 while Playback of the Slave machine to get rid of the stutter. I also recompiled JackD on the master machine from 1.9.12 to 1.9.14 with additional DBUS-support, but it doesn´t make any difference. Firewalls are off while testing. also killed Pulseaudio. Tried to turn off anything which has to do with Speedstepping, set with cpufreqd everything to "performance", no success at all. Even fillding around with sync, async, different Buffer sizes, periods- no chance. Yes, according to the log i recognize the missing data packets, but have no clue what could be the cause - Jack itsef, the Jack Netdriver on the Windows side.... Before Ardour connects to Jackd, i also get a lot of "ProcessGrapMasterASync"-Errors....and sometimes in between. Any help would be greatly appreciated, because i run out of ideas....
