This would be for the sole purpose of audio, and GUI-less ones at that. I also like the idea of being able to carry a studio on a flash drive...sort of amazing. Another machine would have Ardour etc. I
came across the "server core" terminology from the Lubuntu alternate downloads area. So, my impression was a server system is a bit more raw and basic than a desktop system and going with a "core"
version of that would be almost as basic as it gets. I know there are distros tuned for audio, but I honestly don't like all the extra stuff I don't need.

I noticed when running my software that the playback variables are set correctly through Alsa calls, but the record ones are not. It's just the first time the (Presonus) Audiobox has not initialized properly
on probably a dozen systems I have tried it on. I'm assuming the kernel should be the same between a server and a desktop. I works fine on the same 12.04 desktop/Unity version. I wasn't sure if we
needed to run modules or set something a certain way to tap audio capability in a server system. Again, doesn't have to be a sever system at all. I just thought it might be closer to what I am after to
begin with.

Thanks for the help :) See above about the goal here. But again, I crave simplicity and I like to build a system around a specific task and not have one machine do everything.

I'd like to put out a question.
What would seem like the most common channel configuration when using the
module-jackdbus-detect?
module-jackdbus-detect is a module that will detect when jackdbus starts,
and automatically creates a Pulseaudio sink and source for jack. It's a
part of the pulseaudio source, and is separated into its own package on
Debian based distros, called pulseaudio-module-jack.
Currently, it will create as many channels for its sink and source,
separately, as there are channels on your audio device.
Also, it follows the standard model for surround audio, so if you have 8
channels, the module will create a 7.1 interface for the sink and source.
In the case where you have 8 in and 2 out, the module will create 7.1 sink
and stereo source.
In the case where you have more than 8 channels, it will create 7.1 and
add connections named "aux" for each additional channel.
There's now a patch in PA 3.0, written by Peter Nelson, that allows us to
configure how many channels PA should have for both in and out at once.
I'm proposing to have the module be stereo by default. Would this be what
people want?
Thank you Michael.
yes. I have sometnihg with my system.
yaourt and PKGBUILD are ok.
I have to remove some lines about cwiid in ..libs/surfaces/wscript and it
builds nicely.
Now I have ardour3 installed.
I am kinda new in using ardour. Till now I used ardour2 and I was happy.
Are there some problems using ardour3 ? Because I see that it is 3.0rc2.
[update]
ahh. just now reinstalled from cwiid to cwiid-git and ardourd3 builds like
a charm.
thanks

How difficult or even possible is it to start with a server core system
and make it useable for a audio? I don't need a GUI/desktop for this.
I installed Lubuntu server core to a usb flash drive. I added myself to
the audio group, but my usb Audiobox does not seem to be working,
although it is recognised with aplay -l. Should it work without any
additional steps?
I suppose I could build an Arch system, but I was pleasantly surprised
by the performance of Ubuntu 12.04 (desktop) with the particular
software I want to run and thought I would try an even more basic
setup. Thanks!
Hey list,
using jack_capture on an -RT kernel, I see the following message from
the program:
Warning. Could not set higher priority for a SCHED_FIFO process using
setpriority().
How could I set this higher priority?
thank you all,
best, Peter
Thanks Paul, but it stops the config process...
