Trying to get 8 channel sound from Linux Mint and an Intel NUC

by Scott

I am trying to get software control of 8 channels of audio over HDMI. I don't know very much about linux audio software and naively assumed I'd plug an HDMI into an audio converter/splitter and get 8 working outputs. What I get is silence. Someone here must understand this and I'd appreciate help! Here's everything I know about collecting. Sorry for the length or if it's insufficient. Code: wget -O alsa-info.shhttp://www.alsa-project.org/alsa-info.sh && chmod +x ./alsa-info.sh && ./alsa-info.sh http://alsa-project.org/db/?f=9a8a1a...a1d071064900d5 <http://alsa-project.org/db/?f=9a8a1a8f97c09f05356c327bc8a1d071064900d5> Code: uname -r 4.15.0-64-generic #I'm guessing this is what should work, but doesn't: speaker-test -D surround71:CARD=PCH,DEV=0 -c 8 Code: speaker-test 1.1.3 Playback device is surround71:CARD=PCH,DEV=0 Stream parameters are 48000Hz, S16_LE, 8 channels Using 16 octaves of pink noise Channels count (8) not available for playbacks: Invalid argument Setting of hwparams failed: Invalid argument But trying speaker-test -D surround71:CARD=PCH,DEV=0 -c 2 doesn't return errors, but gives silence (even with the SKSL converter set to stereo) pavucontrol Unable to init server: Could not connect: Connection refused (But do I need it?) alsamixer shows Auto-Mute Disabled, Loopback Enabled.

Status of a2jmidid

by Guido Aulisi

Hi, a2jmidid bridges alsa MIDI ports with JACK MIDI ports. It's a quite old and unmaintained? program. Is it still needed with recent JACK2 server or is there an alternative. I know JACK1 has this functionality built-in, what's JACK2 status? Thanks Guido Ciao

Speakers and Schedule

by Sonoj Convention

Ladies and Gentlemen, this years Sonoj Convention is only a month away. (October 27th and 28th). https://www.sonoj.org/register.html Our list of speakers and talks is as good as finished now (except the start times). We will have a live world premiere of an unreleased open source synth (Vital), two talks about sampled instrument creations (Drumgizmo and an sfz bass), a tracker interface for Ardour, a Qtractor introduction by the author himself, modding old speakers into decent ones, the future of JACK and finally a talk about composing tricks and techniques.. On top there is an open slot for surprises! :) As you have read last time there is no visitor number limit anymore. But you still need to register if you want to come. Now is a good time to do just that: Write a mail to info(a)sonoj.org <mailto:info@sonoj.org> or use the website https://www.sonoj.org/register.html . Your name and e-mail address are enough. If you don't have time be aware that the whole event will be live streamed and you can interact with us and other remote visitors through a live chat. A link is already on the website. In the meantime: Have a look at our old recordings and please subscribe to our Youtube channel. https://www.youtube.com/channel/UCRETFHZgyoUMyUxz3k9lrZA/videos Yours, Nils Hilbricht Sonoj Convention

by Rui Nuno Capela

Summer's gone! So is the austral winter... The 'Vee One Suite' of so called 'old-school' software instruments are now released for the Northern Fall/Autumn season: * synthv1 0.9.10 [1] * samplv1 0.9.10 [2] * drumkv1 0.9.10 [3] * padthv1 0.9.10 [4] All available in dual form: - a pure stand-alone JACK client with JACK-session [5], NSM (Non Session management [6]) and both JACK MIDI and ALSA MIDI [7] input support; - a LV2 instrument plug-in [8]. Changes for this northern autumn'19 release goes like follows: - Upstream packaging is now split on JACK standalone, LV2 plugin and common core and UI packages, similar to recent Debian practice. - Highlight current element/sample/key on the virtual piano keyboard widget. (applies to samplv1 [2] and drumkv1 [3] only) - Added alternate yet non-official CMake build option. - Fix HiDPI display screen effective support (Qt >= 5.6). - All randomizers now compliant to the standard normal distribution. - Make sure compiler flags comply to c++11 as standard. 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 0.9.10 (early-fall'19) is out! synthv1 is an old-school all-digital 4-oscillator subtractive polyphonic synthesizer with stereo fx.

OT: Amazon Lab 126 and Linux

by Peter P.

I just came across this job posting https://www.amazon.jobs/en/jobs/894336/applied-scientist from Amazon Lab 126 and am positively surprised that they are asking for experience with Alsa, Linux and realtime systems. Lab 126 seems to be an R&D lab contributing to products like Kindle, Fire tablets, Fire TV and Amazon Echo, the speaker for their Alexa service which suffers from severe privacy issues, see https://en.wikipedia.org/wiki/Amazon_Alexa#Privacy_concerns Does anyone know if any of these devices are using Linux as their OS? A quick online research did not confirm nor deny this. Despite Echo/Alexa being a questionable product in my view, as for example described in https://www.engadget.com/2019/04/30/hey-alexa-how-can-we-escape-surveillanc… it would be a great example of widespread use of Linux in an audio product.

Immersive Audio, ADM and MPEG-H

by Christoph Kuhr

Hi *, I am attending an MPEG-H workshop with the Fraunhofer IIS Soundlab. MPEG-H shall be used for immersive audio and assistive technologies in DVB technologies (and hopefully more). At the moment, there is no Linux plugin. Only au and vst. But, an engineer of Fraunhofer offered me that he would initiate a Linux plugin development if I can find more then three people, who are interested. I took this bet! So please support me! :-) BR, Ck

A bit of 2013 nostalgia!

by Louigi Verona

Hey everyone! I have recovered three tracks that I made during LAC2013. Restored from their sorry state to something more palatable, these 10 minutes of music will allow you to join me on this nostalgic journey and reminisce about times long gone! https://soundcloud.com/louigiverona/sets/lac2013 On track one you can hear samples taken out of the lecture by Rui on QStuff, which I recorded with a mic right there and immediately incorporated into the music. "You are the user!" This is true Linux Audio community lore :D Louigi Verona https://louigiverona.com/

[Music] Prophetess on holiday

Hey hey, a new synthpop tune. Someone said it sounds 80ish, although I aimed for the naughties. It's all one hardware synth, sequenced, recorded, mixed and master in Linux with my usual setup. youtu.be/p_dol1TI13Y I hope you enjoy it, whether for its sounds or the music. I'm looking forward to your impressions, if you have any. :) Best wishes and enjoy, Jeanette -- * Website: http://juliencoder.de - for summer is a state of sound * SoundCloud: https://soundcloud.com/jeanette_c * Youtube: https://www.youtube.com/channel/UCMS4rfGrTwz8W7jhC1Jnv7g * GitHub: https://github.com/jeanette-c * Twitter: https://twitter.com/jeanette_c_s I believe We all have one true love Somewhere in this world <3 (Britney Spears)
