Headless jackdbus (no X11)

by Len Ovens

I have in the past used something like a jackstart script in a headless situation before, which started dbus and exported it's info so jackdbus would work. It is actually easier to use: dbus-launch screen Then use screen as your CLI session manager. jack_control can then be used to run jack and change settings on the fly (like latency?). Audio applications can be run in other screen terminals to use jack... and if you really want to go crazy you can throw pulse at the mix... though I am really not sure what pulse supporting applications you hope to find that are CLI (I tested it with paplay, but there is no gain using that over jack.play). -- Len Ovens www.OvenWerks.net

jack CD ripping: coding failed, err#8

by Peter P.

Hi, using the jack command line CD ripping program, the extraction from CD audio to wav works fine, but the encoder (pre-set to flac in the .jack3rc config file) seems to fail. Jack gives me "coding failed, err#8" for each CD track. Can't find a -verbose or -debug flag to make it tell me more. Any ideas and help is greatly appreciated! best, Peter

Re: [LAU] Zita-ajbridge ?

by Marc Lavallée

Hi Len. I would like to use jackd in 32bit (or is it 24bit, or float?) but output in 16bit (resampled with zita-j2a). This is to play 24bit files with the best possible quality when using multiple 16bit sound cards or USB modules. When starting jackd normally (with the alsa backend and a 16bit sound card), mplayer output is 16bit (that's not what I want). When starting jackd with the dummy backend, or the alsa backend connected to a loop device, jackd works in 32bit float and mplayer output is floatle; jackd doesn't report sync problems and mplayer just plays the file. Then I connect the floatle output of mplayer to zita-j2a, there's no sound. Even when starting jackd with the internal sound card, zita-j2a stays silent. -- Marc Len Ovens <len(a)ovenwerks.org> a écrit : > On Fri, 19 Jul 2013, Marc Lavallée wrote: > > > For some reason, zita-j2a 0.2.2 is silent on my laptop.

Screen blanking

by Ralf Mardorf

Hi :) how can screen blanking be disabled? A long time ago I have given up to check this out for my Ubuntu Studio installs. FWIW it's not the monitor, for an old Suse 11.2 install the screen never will be turned off. Now I try to disable screen blanking on Arch Linux, Xfce 4.10. $ uname -rm 3.8.13-rt14-1-rt x86_64 This doesn't work: $ cat ~/.xinitrc #!/bin/sh # # ~/.xinitrc # # Executed by startx (run your window manager from here) if [ -d /etc/X11/xinit/xinitrc.d ]; then for f in /etc/X11/xinit/xinitrc.d/*; do [ -x "$f" ] && .

Zita-ajbridge ?

by Marc Lavallée

Good evening LAU. This is my first post to the list. For some reason, zita-j2a 0.2.2 is silent on my laptop. I tried it with the built-in sound card and also with a USB module (both are 16bit/48KHz). I started jackd with the alsa and the dummy backends, without success. I even recompiled zita-j2a. What could be the cause? Thanks in advance. -- Marc

Guitarix 0.28.0 released

by Andreas Degert

The Guitarix developers proudly present Guitarix release 0.28.0 "magic chainsaw trick" *) Yes, we took a chainsaw, cut through the chest of Guitarix, and... it's still alive. But now it's also 2 pieces. You can start it (headless) on an embedded ARM system. You can start it on your laptop and connect the user interface the the headless instance. You can even tap on your smartphone and control Guitarix with the web browser (or just use the tuner). For the uninitiated, Guitarix is a tube amplifier simulation for jack, with effect modules and an additional stereo effect chain. Please refer to our project page for more information: http://guitarix.sourceforge.net/ Download Site: http://sourceforge.net/projects/guitarix/ Forum: http://guitarix.sourceforge.net/forum/ Embedded Guitarix Prototype: http://sourceforge.net/apps/mediawiki/guitarix/index.php?title=Guitarix_Emb… Please consider visiting our forum or leaving a message on guitarix-developer(a)lists.sourceforge.net if you plan to work with embedded Guitarix. List of changes: * new french translation contributed by Bajo * new MultiBandCompressor contributed by kokoko3k * new include BestPlugins IR-Packs I-III by David Fau Casquel * new DigitalDelay Effect module * the Guitarix LV2 plugins are now in the default build (but you can configure the build with --no-lv2) * Optimizations for embedded systems / ARM processors with NEON * --faust-vectorize-float, --convolver-ffmpeg * Guitarix headless mode for embedded systems (no X11 / user Interface) * network socket based service for controlling / connecting a user interface * service announcement via Avahi, if available * command line options --rpchost, --rpcport, --nogui * the service can be started in addition to the "local" user interface * Guitarix can now be used as a user interface connecting to a remote instance * no configuration needed if Avahi is available * command line options --onlygui, --rpchost, --rpcport * multiple user interface clients can be started (the displays keep synchronized) * Browser-based user interface (javascript code) * cross platform * usable on small devices like smartphones, and in conjunction with an embedded device * some features still missing (no MIDI controller connections, no presets for single effect units, no polished appearance) * small additional server needed (included), to translate between the socket based interface and WebSockets, which is what (modern) browsers understand * only recent browsers supported, testers needed * released in a separate tarfile *) http://www.youtube.com/watch?v=GPTHdwqG9rw
