Hi list, Since a while (recent kernel or other package upgrades?) I am experiencing serious problems with jackd after resuming from suspend. Eg. trying to play back audio files via mpv yields mpv somefile.flac (+) Audio --aid=1 (flac 2ch 44100Hz) Cannot read socket fd = 13 err = Success CheckRes error JackSocketClientChannel read fail Cannot open mpv client JackShmReadWritePtr1::~JackShmReadWritePtr1 - Init not done for -1, skipping unlock JackShmReadWritePtr::~JackShmReadWritePtr - Init not done for -1, skipping unlock JackShmReadWritePtr::~JackShmReadWritePtr - Init not done for -1, skipping unlock At which point the command hangs. The card used is an Edirol UA-25 connected via usb. I can quit the hanging mpv with Ctl-c, upon another invocation the error persisits but mpv gracefully attempts alsa this time. Qjackctl, which was used to start jackd in the first hand place, is unresponsive as well. I for now kill jackd as root three times to regain control over it after every resume. How can I go about to debug this further? The above problem is with jackd2. Switching to jackd1 will show a slightly different problem upon resume: Using 100% CPU and being unresponsive either. I posted about this in jan/feb 2024 By the way: I can't search in the mailing list archives as the search engine on linuxaudio.org throws a lot of "502 bad gateway" or "504 Gateway Time-out" errors at least for lac and jackd lists: https://lists.linuxaudio.org/hyperkitty/search?mlist=linux-audio-user%40lis… Thanks!

Slow performance of linuxaudio.org servers

And it's under-powered to keep the costs low. If people are (still) willing to donate then I should offer an option to do so I think, that might help increasing the performance of the servers a bit. What is the best option for receiving donations these days? Best, Jeremy

[ANN] Qtractor 1.5.2 - A New-Year'25 Release

by Rui Nuno Capela

Greetings, Qtractor 1.5.2 (new-year'25) released! Change-log: - Duplex MIDI Clock mode is not allowed anymore. - Immediate and consecutive plugin parameter changes are now merged into a single undo-able command, reflecting only the first value change in the series, dropping the previous old algorithm, which was dead wrong if not utterly defective. - Unique track names resolve to the first line only. - Help/Shortcuts... Search tool gets implemented; all changed MIDI controller shortcuts are reverted to their previous settings, when discarding or dismissing the dialog. - Fixed missing MIDI SPP in some cases. Description: Qtractor [1] is an audio/MIDI multi-track sequencer application written in C++ with the Qt framework [2]. Target platform is Linux, where the Jack Audio Connection Kit (JACK [3]) for audio and the Advanced Linux Sound Architecture (ALSA [4]) for MIDI are the main infrastructures to evolve as a fairly-featured Linux desktop audio workstation GUI, specially dedicated to the personal home-studio.

[ANN] Vee One Suite 1.3.0 - A New-Year'25 Release

by Rui Nuno Capela

Greetings, The 'Vee One Suite', the 'gang-of-four' 'old-school' software instruments, * synthv1 [1] as a polyphonic subtractive synthesizer; * samplv1 [2] a polyphonic sampler synthesizer; * drumkv1 [3] as yet another drum-kit sampler; * padthv1 [4] a polyphonic additive synthesizer. Are here released for the New-Year'25 recycle... All still delivered in dual form: - a pure stand-alone JACK client with JACK-session [5], NSM (Non/New Session Management [6]) and both JACK MIDI and ALSA MIDI [7] input support; - a LV2 instrument plug-in [8]. Change-log: - Just another Vee-One's release for the New Year... - Last current element is now preserved and selected on preset and/or LV2 plug-in load (host permiting). (drumkv1 [3] only) - LV2 Plug-in: element parameters as legacy input control ports are not automatable nor addressable from the host anymore. (drumkv1 [3] only) - LV2 Plug-in: avoid making offset and loop range changes as regular parameter updates, which marked the host's state dirty (modified). (applies to samplv1 [2] and drumkv1 [3] only) The 'Vee One Suite' are free, open-source Linux Audio [10] software, distributed under the terms of the GNU General Public License (GPL) [11] version 2 or later. **synthv1 - an old-school polyphonic synthesizer [1] ** synthv1 1.3.0 (new-year'25) released! synthv1 is an old-school all-digital 4-oscillator subtractive polyphonic synthesizer with stereo fx.

[Music] In the face of the |world (melodic Drum&Bass/Soundtrack)

by Jeanette C.

Hey hey, I'd like to share In the Face of the World: https://youtu.be/MVHFCxuSG4o Expect heavy hitting drums, modulating chord progressions and even a bit of polymetric sequencing in the background. Or: just dark, dramatic electronic music. On the Linux side I used Yoshimi, LinuxSampler and Csound, as well as Midish and Nama (of course). I hope you can enjoy it. Best wishes, Jeanette -- * Website: http://juliencoder.de - for summer is a state of sound * Youtube: https://www.youtube.com/channel/UCMS4rfGrTwz8W7jhC1Jnv7g * Audiobombs: https://www.audiobombs.com/users/jeanette_c * GitHub: https://github.com/jeanette-c You know I'm one of a kind, There'll never be another me <3 (Britney Spears)

AVB on Linux and Biamp products

by Joshua Boyd

On ebay I see a bunch of Biamp products with AVB support. While their products seem to be more conference room oriented, I keep wondering about using them with Linux, possibly for monitor management. I know I've seen people talk about using AVB with Motu products, but I don't think I've ever seen anyone mention using AVB with other products, such as Presonus, Biamp, or macOS. I just want audio networking to be accessible, and AVB looks like it is the closet to being so.

by Rui Nuno Capela

Hi again, Qtractor 1.5.1 (end-of-year'24) is out!
