jitsi-meet videoconferencing and jackd losing mic input

by Peter P.

Hi, for the last two years I was able to run the excellent and floss jitsi-meet videoconferencing tool using the jack audio server by installing the "jack" alsa plugin, and telling jitsi-meet to use it as default via my ~/.asoundrc holding the following: pcm.!default{ type plug slave { pcm "jack" } hint {description" jack with software conversions added by me" } } Since the last two or three jitsi-meet upgrades (which are hard to trace because they happen forcibly and in the background without user notification) the software will lose its microphone input a few seconds after the mic is unmuted, tracable by a vanishing audio connection in jack's gui qjackctl. When this happens I see jackd posting subgraph starting at alsa-jack.jackC.468772.0 timed out (subgraph_wait_fd=17, status = 0, state = Triggered, pollret = 0 revents = 0x0) 09:27:13.048 JACK connection graph change. **** alsa_pcm: xrun of at least 393698.976 msecs 09:27:13.052 XRUN callback (8). 09:27:13.232 JACK connection change How can I go about debugging this further? Thank you a lot! P

[music] Let's dance (on four): disco funk with romantic piano

by Jeanette C.

Hey hey, I'd like to present let's dance (on four): https://youtu.be/mXjZJasO00M OGG version: https://www.dropbox.com/s/w3l8fy0zy5y1nq8/lets_dance-on_four.ogg This piece takes many inspirations in style and melodies, though it is not a cover of anything. The style is taken from 70s disco funk as played by the Munich Music Machine, a collecitve who cover classical pieces in their style. The piano theme is inspired by late romantic piano compositions. There are actually two small quotations from radio jingles of old (until early/mid 90s) from the public German radio station WDR4, which explains the title. Technically, LinuxSampler brings us the grand piano and the electric ones (both Rhodes and Wurlitzer) as well as the drums. The drum kit was especially assembled for this tune. The bass is courtesey of Fluidsynth and the naturally decaying bass soundfont. Yoshimi perfectly shines as a string machine. Both arpeggios and lead synths are hardware, the Behringer Neutron and Aruturia MiniBrute 2s. In terms of plugins, I had to discover a few new ones and find new uses for old horses to achieve that distinct 70s sound. Even with good raw material it took quite a bit of processing to approximate the sound to the best of my abilities. Judge for yourself...

[music] Heroine (soundtrack/synth/baroque)

by Jeanette C.

Hey hey, I'd like to present: Heroine https://youtu.be/rOKoHH8cuCM OGG version: https://www.dropbox.com/s/df3qm4olf2rvmjv/heroine.ogg Special mentions go to Yoshimi for superb plucks, additive synthesis and indispensible layering. Also to the Roland JV-1080 sound module for a powerful architecture, especially considering its year of birth in 1994. Add LinuxSampler, more hardware and the usual stock of great effects and we have a song. This song has two distinct inspirations: technically it is a study in fades and blends and there is still lots more to learn on that score. Musically, there was an old piece I always wanted to explore in a soundtrack like setting. The whole track works up to it, even though the master piece itself only gets a short but explicit spot at the end. Curious? I hope so. :) 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 All you people look at me like I'm a little girl.

Another stab at OSC control of non-mixer

by Jonathan Brickman

Greetings, all. I'm trying to take another stab at OSC control of non-mixer. I've tried a few times over years, always using specific methods given on list or various web sites. I did it again, still no dice. Perhaps someone might be able to tell what I'm doing wrong. First of all, the non-mixer setup I'm using is pictured here: https://img.onl/IQ1Ds8 One of its strips is named "DistortionOutput", another "CleanOutput". The goal is to get outside input somehow (this is a headless design, am currently thinking programmable keypad for maximum simplicity), with two different scripts to spawn, "DistortionMode.py" and "CleanMode.py". My latest attempt, was to run non-mixer with the appropriate command line option for the port, and then once running, to run the script below. It was thought that it would turn the volume of DistortionOutput to zero. However, the script freezes once run and no change is observed. I have made sure the OS firewall is off (Manjaro seems to have it off by default) and have tried a telnet to localhost at that port also, no connection. Thoughts, anyone? -- *Jonathan E.

New soundbank for Yoshimi

by Jeanette C.

Hey hey, today I released Jeanny's Genius for Yoshimi, version 0.5 with 68 single instruments - including three drumkits - and three patchsets. http://juliencoder.de/sound/jg_yoshimi_patches-0.5.tar.bz2 All sounds are categorised and include contact information in the copyright field, in case of issues or feedback. The sounds have been tested with 2.1.2, but should be compatible with Yoshimi 1.5.x. This version includes the star choir patches, based on live vocal recordings. These can be heard prominently in "Lovestruck": https://youtu.be/QX0TnD4VMzQ As well as all Yoshimi sounds used in Silver, my entry for the lst open source Nexus Music Challenge: https://youtu.be/vJLG409oDek And the sounds used from Yoshimi's birthday song: https://youtu.be/0luuMWOYBV0 Share and enjoy, 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 Here I go, on my own now <3 (Britney Spears)

Any 'transport aware' jack-play alternatives?

by John Murphy

I have a slight problem using jack-play since I'm using Pipewire and I wonder if anyone knows of an alternative I could try. pw-play is unsuitable because it isn't transport aware. I reported the bug / problem I have at: https://gitlab.freedesktop.org/pipewire/pipewire/-/issues/2089 It's an odd one. -- John.

Connect pipewire to running JACK server

by Jeanette C.

Hey hey, this is only tangential to the other big pipewire thread. I wish to run pipewire on top of my running jack server as a replacement for pulseaudio, since that somehow stopped working and now I have no speech output from the desktop/Orca. I read that one has to change alsa-monitor.conf for the media session manager. Changing: alsa.jack-device = false to alsa.jack-device = true Which I did, but the next step of using pw-cli to connect or enable it is unclear to me. I will need a commandline way of achieving this. At the moment pipewire is still using ALSA and that means the built-in soundcard which has no connections. Has someone here managed this?
