[LAU] retire_capture_urb: xxxx callbacks suppressed

by Kai Hendry

Hi there, On my T480s on Archlinux I often have issues with my USB microphone (h1 handy recorder): Sep 14 19:00:57 t480s kernel: retire_capture_urb: 2477 callbacks suppressed Sep 14 19:01:02 t480s kernel: retire_capture_urb: 2480 callbacks suppressed Sep 14 19:01:07 t480s kernel: retire_capture_urb: 2479 callbacks suppressed Resulting in just noise / garbage when recording with an ffmpeg/pulseaudio based script: https://github.com/kaihendry/recordmydesktop2.0/blob/master/x11capture https://s.natalian.org/2018-09-14/noise.mp4 It's difficult to reproduce, but I have managed to experience the issue again and again on stable kernels, e.g. Linux t480s 4.18.6-arch1-1-ARCH #1 SMP PREEMPT Wed Sep 5 11:54:09 UTC 2018 x86_64 GNU/Linux But not (yet) upon linux-lts 4.14.69-1 aka "LTS". Any tips how I should proceed here? https://www.kernel.org/doc/linux/REPORTING-BUGS is a bit overwhelming. Many thanks,

[LAU] Berlin Linux Audio meeting @ c-base 2018-09-11

by Daniel Swärd

Hi all. Next meeting at c-base is on Tuesday 2018-09-11. I'll be in the mainhall (or depending on weather) outside from 20:30 as usual. At the last meeting we were discussing if we should do something at the next meeting instead of just talking, and there were some suggestions: - Start defining a standard for communicating midi messages via OSC. - Test out some fun audio projects in the soundlab and/or do some jamming with Linux Audio projects· If we're going to go down to the soundlab, I'd suggest that we collect people in the mainhall/outside between 20:30 and 21:00 before going downstairs. What do you say? If going down to the soundlab, I'll reserve it for us. Cheers /Daniel

Because publicity is the true gospel of the modern times, the true gospel of our society of mass consumption. Even in Cuba, ordinary peoples don't give a penny for both the Marxism or the Capitalism, but they do want to be like us, part of the mass consumption, and that even if it is a madness of the extreme kind that kill the planet at an exponentially industrial rate. Like in the publicity, almost every body want more. And more, and more. And whoa! with internet, the pub is in HD, but it will never show you the enslaved children in the bottom of the mines (it is more slaves on Earth today than ever in History, and their number is growing fast), or the global and systematic destruction of Nature to make these mines, roads, plants, houses, infrastructures of all kinds, nor that this industrial mass consumption society is the best way to make Nature to return at it's mineral state. After us, the new intelligent specie will be robots, a mineral intelligence that will reign onto a mineral world where even the cyborgs will be extermninated. bip bip! > _______________________________________________ > Linux-audio-user mailing list > Linux-audio-user(a)lists.linuxaudio.org > https://lists.linuxaudio.org/listinfo/linux-audio-user -- If you have a problem and you are not doing anything to fix it, you are at the heart of the problem.

[LAU] Libre Music Production still active?

by Christopher Arndt

Hi there, does anybody know, whether the http://libremusicproduction.com/ site is still active? The last post is from February (which just says that the site is back online :-/) and the last tweet from December 2017. Also the comments on the site are riddled with spam. I tried to submit a story via the contact form on the site and the site displayed a message that my form submission was successful but also an error message that the message could *not* be sent. *confused* Who's behind the site? Is there another way to contact him/her/them? Chris

[LAU] [ANN] Qtractor 0.9.2 - The Summer'18 Release

by Rui Nuno Capela

At last! Qtractor 0.9.2 (summer'18 beta) is released! Not much has changed but here's the change-log: - AppData/AppStream metadata is now settled under an all permisssive license (FSFAP); also updated to be the most compliant with latest freedesktop.org specification and recommendation. - Fix build for Qt >= 5.11.0 (by David Geiger, thanks); also for some g++ >= 8.1.1 warnings and quietness. 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.

If you used poppy seed juice rather than cat videos, you'd get stopped before becoming the highest valued company on the planet. Though to be fair, Coca-Cola got pretty far even before reducing the cocaine content of their drink to trace amounts. > Why are many people staring down at their smartphones running private > companies' communication between elements of the masses ? Because said companies are providing products/value that people are willing to pay for. In the case of all that messenger apps, you can trade in your privacy for cheaper connections rather than using the regular phone services (and/or SMS). -- David Kastrup

[LAU] [semi-OT] VLC for mobile question

by Jeanette C.

Hey hey, I know it's not specifically on Linux anymore, but does anyone know fi the VLC for mobile player can play music based on folders rather than tags? I had a look, but couldn't find anything on an idevice. Alternatively: is there perhaps another soltuion for a portable player that will be mounted on Linux and speak? I had a Rockbox enabled player for a while, but it's dying and the players that are usable to me and support Rockbox are a dying breed.

[LAU] mpv af channelmap help

by Jeanette C.

Hey hey, I've been trying to insert an audiofilter in mpv, through the commandline and failed miserably. Can you help? the only thing I wished to do is reverse the stereo channels, because my amp is actually plugged in the wrong way round and I can't change it. From my understanding of the help I typed: mpv --af channelmap:map="0,1,1,0":channeml_layout=2 file.wav The channelmap can't be parsed. Whatever I do. I can get a mono output with just one number. I also get some output with two numbers seperated by a dash "-", but no more. I also tried just giving two comma seperated numbers, i.e. only the new order of the input channels. I'd be grateful for a working example. My shell is bash.

by Carlo Ascani

Hi all, I am considering a Soundcraft Notepad 12 FX [1] as my main laptop audio interface. Is anyone aware about its Linux compatibility and software reliability? Being able to do some multi track recording would be awesome.
