jack2 + arch trouble

by Atte André Jensen

Hi I had some problems with my jack recently, and today something new happened, that I'm actually able to reproduce: In ardour2 "export range markers to multiple audiofiles", *but press cancel before it's finished*. I tried various settings, for instance both wav/flac and 44.100/48.000 (my jack sample rate). After this ardour still plays at more-than-normal-speed (no sound is heard), like it's still rendering, although the dialog disappears. I can force ardour stop playback py pressing the close button of the window, but it only stopps rolling, after a while a "this window might be busy and is not responding" dialog is shown, cliking "yes" (I'd like to force quit it) will exit ardour. Now to the actual strangeness: At this point jackd is screwed, I cannot start clients, it seems like jackd is not running to them. qjackctl looks ok, but if I switch to another workspace and back it's gui is all grey and I cannot exit it, except with the killall command. Top shows jackd is still running, but I can't killall it, even logging out of my xfce session and back in leaves it running. So I need to reboot to use jack again. I'm 99% sure it's not ardour, since this also happened with other clients, although not at consistent and I haven't been able to reproduce it before. Some info: atte@blokhus:~$ cat ~/.jackdrc /usr/bin/jackd -v -P85 -t2000 -dfirewire -r48000 -p256 -n2 atte@blokhus:~$ jackd --version jackdmp 1.9.8 Copyright 2001-2005 Paul Davis and others.

I'm running arch linux on a thinkpad X61s, and I'm pretty sure the system was running fine about a month ago... Any ideas or suggestions would be highly appreciated :-) -- Atte http://atte.dk http://modlys.dk

Netjack with more than two channels?

by Eric Steinberg

I have two machines. On master I do this- launch jack with firewire driver, then in a terminal type jack_load netmanager .....which returns a message that netmanager is running. Then on the slave I launch jack with the "net" driver. So far so good- I can then see connections on the master, hear Hydrogen, run audio from my fa-101 through Guitarix on the slave, etc. All good, acceptable latency. HOWEVER, when i specify 8 channels of i/o on the slave i still get only two channels in both master and slave connection diagrams. How can I get MOAR?

aur packages with lash dependencies

by James Morris

Hi, Just wondering if there's any particular reason why so many Arch Linux AUR packages list LASH as a dependency? Seems they all (or those I've tried so far) build fine without it. Additionally I understood LASH to be deprecated. Just saying! James.

A tune about nothing

by Louigi Verona

Hey everyone ) So I was sitting there, Friday afternoon, not much to do. So I started playing around with Linux Audio software and you know where that might lead you at times! Anyway, I thought - is it possible to make a tune with no melody whatsoever and not too much development BUT with drums and a bassline. Seemed like a challenge and I took it. The result is this tune, a tune about nothing. http://www.louigiverona.ru/files/nothing.ogg Enjoy(possibly)! -- Louigi Verona http://www.louigiverona.ru/

usb interface 4+ out channels?

by joachim heintz

hi all - i do urgently need a (professional) usb audio interface for my linux laptop (ubuntu 11.04). i need at least 4 seperate output channels. i don't have an express card slot or firewire. i have looked at the alsa site and read many threads, but i couldn't find any option which fits for my needs (emu0404 seems to work but needs an additional digital-analog-converter). any tip is very much appreciated. joachim

Fluidsynth midi player start at time or tickindex?

by Nils

Hello, Does anyone know how to tell fluidsynth to start playing at a certain point in the file? By time or even midi ticks? I use fluidsynth as standalone midi player because I need no daemon running and can give the soundfont in the commandline, so trying out different soundfonts is very easy. If not I would like to hear about your midi player solutions. The less config files and servers, the more I can set parameters directly on the command line, the better. Nils
