Linux Audio the way to go!?

[SunRa]

I can avoid the volume control issues as it's done in the amp! I can avoid the DAC issues as it's done in the amp! My main concern then is low jitter dig signal to the amp. Unfortunately I2S is not easy to tap into on the amp or I would go that route from the USB soundcard.

Hello jkeny,

what about this ? Is this of any help for you?

[.: ZMN :.]

there is a description here:

All applications deemed nessessary to provide a working PC studio environment. This is the package most users of other derivatives will be interested in, so they don't get forced into a different desktop environment with a new theme and such.

If I understood correctly, Ubuntu studio provides the cool audio/video/3d packages together with an optimized system configuration for multimedia. Adding the real-time kernel is a part of that optimization.
Correct me if I am wrong, but I think you should be able to install the RealTime kernel-image package (linux-image-rt) to add real-time kernel functionality to a normal Hardy, without adding the additional ubuntustudio applications.

Hi Jkeny,

You can install the real time kernel on normal ubuntu/xubuntu/kubuntu etc. They are all currently hardy, so is the latest Ubuntu Studio, just with the real-time kernel, a pre-selected set of audio/graphics/video applications and different artwork theme already installed. The ZEN kernel suggested by soundcheck can also be installed on any of the *ubuntus (afaik).

The emu 0404 usb is close to being supported through alsa, in fact I have one and its works - not yet optimally, but should be soon enough (or so I hope). The way its usb is implemented should theoretically have lower jitter than the pcm2707 because it acts as the master - the clocks confirmed as low jitter crysteks. It has toslink/coaxial spdif out/in and can be slaved to an external clock through spdif. Not diy, but to me, great value.

Thanks SunRa, my model is different & not so easy to get at I2S lines!

ZMN, is there a link to this? Can I just install the real-time kernal & audio aps to Hardy without the video, etc or would it be easier to install ubuntu-studio & remove video apss,etc? Edit: Sorry just read your link & my Q is answered - but is there a distro which just deals with standard audio playback without MIDI, sequencing, DJ stuff,etc

rossco, I will lookat EMU 0404 but my final solution will be PeuFeu's audio over ethernet

Edit: my final question - where do I download ubuntu-studio audio?

jkeny,

if you do not want the video apps, just do not install them.

Look at dependencies of the ubuntustudio-audio package

http://packages.ubuntu.com/hardy/ubuntustudio-audio

It lists all the packages required (i.e. installed) by this meta-package. Just install the packages you want over regular ubuntu. If you want the real-time kernel, add the linux-rt package too (it is one of the dependencies of ubuntustudio-audio). You will have both the kernels installed and can boot from either of them.

Ubuntu, Ubuntu Studio, Edubuntu, Kubuntu, Xubuntu differ just in some packages and you can freely convert from one to another by installing/removing appropriate packages from their common repository.

jkeny,

Phofman explained the background more clearly than I can.

But if you are looking for a way to install the meta-package "ubuntustudio-audio" or just only a selection of the packages you could use a menu driven package manager, like:

System -> Administration -> Synaptic Package Manager.

Then, within this package manager, do a search on "ubuntustudio" to see all related meta-packages for Ubuntu studio. Or search "linux-image-rt" for just the real time kernel image. If you mark them (checkbox), the dependencies will be selected as well. You can then choose to install these selected packages.

I know this is a dumb question but how do I create a bootable DVD from the ubuntostudio.iso image I downloaded. I tried using Roxio but it's a load of c**p.

Is there a simple foolproof way - I know it should be easy but ...................

Problem solved!!!!!

[soundcheck]

If you write the .iso image to disc, the disc is bootable.

There must be an option somewhere, which says "write ISO image", even in Roxio.

Cheers

Oops, problem not solved - in Roxio there's an option to make a bootable disk - it defaults to display .img files - I change it to all files, select the ubuntustudio.iso downloaded & write disk - result is another drinks coaster - error msg when booting "missing operating system"

Hi there.

Two points I'd like to make:

1.
Installing the packages might not be as good as installing
UStudio from scratch. The Gnome setup for UStudio is very
slim and causing less "WakeUps". You'll see that e.g. most of the gadgets are taken out of the desktop environment.
Though if you install the full package from the repositories and you select it as a seperate Xsession before logging in , there shouldn't be a difference compared to a maiden UStudio DVD installation.

The way I do it:
First I install UStudio and than everything else I need (Openoffice etc.) I keep loging all applications I am installing on top of the
standard Ubuntu environment and save it in a file (script).

The first I do is running this script doing an apt-get install ..........
for numerous additional packages.




2.
People who would like to try the RAM playpack, can do it very
easy by just copying a file to /dev/shm (shared memory)

With your player of choice you just go to that directory and pick your file for playpack.
