May be this is a good point. But I don't dig with it, just stop to use new kernels temporarily and still using 2.6.31-rt One more significant(for me) reason for still using 2.6.31, except nvidia-problem, is that I find out that command ps output was somehow changed in subsequent kernels, so steps starts from 3 from http://subversion.ffado.org/wiki/IrqPriorities is not working. -- Truly yours, Oleg Ivanenko aka Ash [if it wasn't so sad, it would be funny] -- Ubuntu-Studio-users mailing list Ubuntu-Studio-users@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-studio-users

I just wonder a little bit, because for an audio distro there might be some hacks, that are different from an averaged desktop distro. IMO mixing tickets for desktop computers and audio studio computers could lead away from the target to get a stable audio and video production Linux, because 'democracy' does mean to fit to the needs of the most people, but just a minority group needs real time audio. - Ralf -- Ubuntu-Studio-users mailing list Ubuntu-Studio-users@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-studio-users

Is your machine an AMD dual core too and is the architecture of your 64 Studio also amd64, but x86? Perhaps it has to do with the NVIDIA graphics? Perhaps I should generate a xorg.conf by running 'sudo X -configure' and test the vesa driver. I dunno.

PulseAudio
A last newbie posting. I surfed the devel mailing list archive. https://lists.ubuntu.com/archives/ubuntu-studio-devel/2010-February/002220.html For 64 Studio (AFAIK it's the only audio distro beside Ubuntu Studio, that is based on a .deb system and supports amd64 architecture, but only i386), PulseAudio is disabled. It's making things much easier for users. OT: To have the choice between JACK1 and JACK2 would be good to, AFAIK there's no distro supporting this. - Ralf -- Ubuntu-Studio-users mailing list Ubuntu-Studio-users@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-studio-users

Electroacoustic Collaboration
Hi All, I'm working on an International Electro-acoustic Collaboration with authors around the world. The piece consists of different languages being processed and completely transformed by the five composers. We are currently recording different voices, and I wondered if anyone in the Ubuntu Studio community has a small studio and speaks a language other than English and would like to participate by recording his/her voice. Only a few sentences would suffice and what is said is entirely arbitrary. Ie, maybe talk about something that you have a passion for, or whatever you etc. The important thing would be that the recording sounds good enough (ie, ideally recorded with a condenser, without any background noise) I'll be using open source software and my Ubuntu Studio machine to process the material. The finished result will be available to listen online and will be played in different concerts in Latin America and Europe, with possibilities of it being played on some European radios too! If you want to find out more about electro-acoustic music, google it or follow this link: http://silver-sounds.com/electroacoustic-def.php If you have any questions, or want to volunteer, just email me @ producjohns AT gmail DOT com There's about 2 weeks at the most before the composition begins so it would be great to have recordings by the end of this week.
