I every one,
I'm new with jack . Just dowload JACK 1.9.18 macOS-universal
<https://github.com/jackaudio/jack2-releases/releases/download/v1.9.18/jack2…>.
to use it with my mac book pro M1 (big sur).
Download also supperlooper.
When i open jack, it shows my interface (sound card UAD appolo) but when i
open superlooper, it says "connection error, no response from superlooper"
I tried to open other software like uad luna or garage band, but they dont
show in jack neither

Do you know how i can have Jack to work ?
Thanks a lot for you help,

Hi Marko et alii,
I guess it came from the usb-device.
Seems the device do not handle the power off properly.
(usb-bus get out of sync)
It may help to power off the usb-ports in sleep-mode. (disable the charge function in bios)
A simple test may be to disconnect & connect the device after resume.

Hi,
I'm using a Blue Snowball that I activate with a script
#!/usr/bin/zsh
HARDWARE_ADDRESS=`arecord -l | grep "Blue Snowball" | sed -e "s|card \([[:digit:]]\).*Blue Snowball.*device \([[:digit:]]\).*|\1,\2|"`
case $1 in
"jack")
alsa_in -d hw:$HARDWARE_ADDRESS -c 1 -p 512 >/dev/null &
sleep 2
jack_connect "alsa_in:capture_1" "PulseAudio JACK Source:front-left"
jack_connect "alsa_in:capture_1" "PulseAudio JACK Source:front-right"
;;
"monitor")
jack_connect "alsa_in:capture_1" "system:playback_1"
jack_connect "alsa_in:capture_1" "system:playback_2"
;;
*)
pkill -f "alsa_in -d hw:$HARDWARE_ADDRESS" || true
;;
esac
When I forget to have the script kill alsa_in and I suspend the computer
it hangs upon resume. This is using Manjaro/KDE. WHat would be the
recommended way to fix this?
Thanks in advance.

Hi guys,
I’m contributing to librespot, which you might know as an open source client library for Spotify, and am writing you for your help to test changes to its JACK backend.
I’m no JACK user myself and trying to test for regressions in a patch that handles Spotify samples in 32-bit floats instead of 16-bit integers (for doing volume control and normalization). However, I'm not getting any sound and wondering if I am doing this right.
I’ve installed jackd2 1.9.12 on Raspian 10. I’ve got a working Alsa setup that outputs to an external DAC over I2S. I launched with “ jackd -dalsa -s -r 44100” and can hear a test tone playing when executing “jack_simple_client”. So far, so good.
However, I’m not getting any sound (or errors) when launching playing music with librespot launched with “—name test --verbose --backend jack audio --disable-audio-cache”. This is both on my branch of work [1] as it is on the untouched development branch [2].
Is there anything else I need to set up? Or better yet, could any librespot users chime in?
Thanking you in advance,
Roderick

Hi all,
Please refer to this thread on linuxmusicians.com forum, starting here:
re. Non-Session-Manager fork descalation
https://linuxmusicians.com/viewtopic.php?p=130477#p130477
I'm not willing to open and engage into yet another discussion about the
so called "NSM fork", though I still don't understand what jackaudio.org
has to do with the new(er)-session-management (aka "NSM fork") and why
it is now moved from linuxaudio.org to jackaudio.org.
I don't like it and as I said before (on #jack irc), it won't get my
vote in: please don't make the same mistake again and keep jackaudio.org
away from this diatribe.
So please, host it on its own website, or github.com page, or on
kx.studio or laborejo.org, as these are the proper to the main two
proponents to "the fork".
Thanks for listening

Dear All,
I am developing a software synthesiser.
My question is about how much headroom I need to leave.
My understanding is:
1. The audio range is from -1.0 to 1.0 (yes/no?).
2. Anything above 1.0 or below -1.0 will be clipped.
3. If the audio interface is 16 bit, then -1.0 corresponds to -32768 and
1.0 corresponds to 32767.
4. If I play a note on a synthesiser and it generate sine wave from -1.0
to 1.0 then this is no good. I need to divide it by some number to leave
a headroom.
5. The question is, how much headroom I need?
Any help would be appreciated.
With kind regards,
Robert
Hello, all, newbie here, both to this forum and to music. I'm a first
year music theory student at my local community college.
I'm searching for a definitive answer to the question, How to play
sounds from a MIDI controller to the other participants in a Zoom
video-conference? I've successfully hooked up my Korg microKEY
controller to my Ubuntu 18.04.5 computer, using qjackctl 0.4.5, qsynth
0.5.0 and vmpk 0.4.0. I connect the microKEY2 to the qsynth and the
VMPK. The patchbay is set up with these connections:
Output Input
PulseAudio JACK Sink and qsynth connect to system
a2j 2 connected to a2j 2
Midi Through and microKEY2 connected to a2midid
I can hear the synthesized piano in my headphones and see the VMPK keys
activate. So far, so good.
I'm using Zoom 5.4.9. I tried to follow the instructions at
https://www.reddit.com/r/linuxaudio/comments/gckoia/midi_to_zoom_skype_etc/.
I used paprefs to add simultaneous output on all sound cards. In this
configuration, when I start Zoom and go to Settings and Audio, I cannot
hear the Test Speaker sound, but can still hear my piano. When I connect
to a meeting, the other participant can't hear me or the piano, and I
can't hear them. I don't know what's meant by "open pavucontrol and
under playback make qsynth output to the null sink. Under recording make
the videochat application use the monitor of the null sink." These seem
to be instruction for JACK, not pavucontrol.
I've seen references to Carla, but it doesn't seem to be in my Ubuntu
repository, and doesn't seem to be created for Ubuntu 18.04.
Can anyone give me an insight to what I'm doing wrong and how to correct
it? My normal troubleshooting technique of just try every possible
combination until something works fails at this task; there's just too
many moving parts.
Thanks so much for your advice and guidance. Let me know if there's a
more appropriate place to ask this question.

Hello,
I use jack2, but still have the jackrouter plugin in my OS X plugin folder. I am trying to understand if this is suppled by jack2, or is a hangover from jackosx. Either way it works.
Thanks
