Re: [Jackaudio] hang upon suspend/resume with USB microphone

by Karsten

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.

[Jackaudio] hang upon suspend/resume with USB microphone

by Marko Schuetz-Schmuck

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. Marko

[Jackaudio] Help testing librespot backend

by Roderick van Domburg

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 [1] https://github.com/librespot-org/librespot/pull/660 [2] https://github.com/librespot-org/librespot

[Jackaudio] new-session-management on jackaudio.org

by Rui Nuno Capela

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 -- rncbc aka.

[Jackaudio] Headroom.

by Robert Wolf

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
