Default the "input" of the soundcard is actually an "output" in Jack, called Readable Clients

If you think of the soundcard as a speaker, that might help. A speaker has an input, but the speaker itself is an output device. Where a speaker takes an analog signal and converts it to sound-pressure that we can hear, a soundcard takes a bunch of bits, from a CD or softsynth or mp2/3/4, etc, and converts it to analog for speakers or other audio gear. A soundcard also coverts in the other direction, from audio to bits for CDs, mp3s, etc. Although I'm only a few months into the penguin's audio world, I am blown away by the power of Jack and the lameness of Windows to provide anything similar - even leaving money out of the equation. Maybe ReWire is similar, but Windows audio routing is so much LESS intuitive than Jack, I am a total
convert now. I didn't even mention how all my MIDI USB gear is true plug-n-play in Ubuntu Studio, thanks to Jack, whereas in Windows, I was constantly tweaking drivers and hunting for updates to keep things compatable or to get them to work at all. Jack is smart and simple, and it works.

Ok, as long as there is only green 0 (0) below 'Started' and no red
numbers, everything's fine. The yellow % numbers are cpu-load. It
shouldn't be at 70% but rather fairly below 10%.

When getting a soundcard, make sure it is compatible. The best place to
check that is: http://alsa-project.org/main/index.php/Matrix:Main

The main strengths of the jack system are the possibility to get really
low latencies and very flexible routing. If you don't have high
requirements, single applications using alsa might suffice.
For loop-based and straight stuff, lmms could be a all-in-one option
(similar to fruity loops), but beware that it's still pretty early in
development and that
it's not in Ubuntu Studio by default.
Try and test, find out what works for you. It could be interconnecting
apps using jack or a single app that does it for you, try, try, try,
and ask.

#1 seems like a no-brainer, but... My installation changes this setting every
time I boot. Since I have a Delta 1010LT, I select ICE1712 (the chipset on the
Delta).

I start Jack, then I open the Envy24 control panel for the soundcard, then I
open Ardour. The audio in and out of Ardour is adjusted on the Envy 24. There
is also a monitor input selector on Envy24. The
cables from the Delta 1010LT
aren't fully labeled, near as I can tell.

This information is what I have needed at bare minimum to get the editor
working. As I can get sound in and out, I'm now at the stage where I'm
learning to "edit" on Ardour.

Well I got a little further with your info ...like that I am getting the

xrun
thing is a problem so I am not there yet.
I think I have decided to install ubuntustudio on my other machine that has
ubuntu 7.10 on it but I don't know how to update from a dvd. The other
machine has a good soundcard so that would solve a lot.

Thanks but I have bashed my head too long and it hurts. I really don't
understand alsa or anything sound wise in linux. I have decided to install
ubuntustudio on my other machine as it has the better soundcard (well not
soundonboard) and more ram too. I just don't know how to upgrade from a dvd
via the respositories.

Carla. By the looks of it, your sound card is compatible. If you haven't
already, you need to understand what Jack is for. If you've used Re-Wire
in
the Windoze world, it's like that but better. It's used to route
("wire")
audio inputs and outputs between the music programs and the soundcard, so
it's actually your patchbay. It's also used to synchronize tempo
of
the
multiple music programs you choose.

For instance I use Ardour to record. To route inputs from the soundcard, I
go to Jack, click "connect" and connect the soundcard inputs on the
left
panel (which might appear as 'capture_1' and 'capture_2' under
'alsa_pcm' or
'system') to the tracks I created in Ardour on the right that appear
under
'ardour'. You will probably need to click on the [+] to expand and see
the
individual connections under each program you see in Jack. You simply
connect these inputs and outputs by click-dragging between them. Ardour
depends on Jack to connect all its tracks to it's master output and
bus'es
too. You disconnect by clicking on both sides of the connection and
clicking disconnect. Don't click Disconnect All unless you really mean to
Disconnect All.

So to not get confused, the "input" of the soundcard is actually an
"output"
in Jack, called
Readable Clients which makes more sense said that way. The
Writeable Clients such as your soundcard output "system or alsa_pcm",
is an
Input in Jack but a physical output respectively. Look at like the
'inputs'
to your 'outputs' and the 'outputs' of your 'inputs'.

For each Jack-aware music app (eg. Hydrogen), you'll also see them in the
Jack connections panel. To understand what Alsa is in the Linux world,
Instead of getting a driver for windows from that soundcard's website, Alsa
is the sound driver(s) for all the different sound cards our there, a
one-for-all(most actually), instead of one-for-one in the shitty windows
world. If you get any sound without Jack (ie. the startup sound), your card
is working and you really don't need to understand more about Alsa. Hope
that helps.

Default the "input" of the soundcard is actually an "output" in Jack, called Readable Clients

Mmmmm that makes sense. I guess I just also don't understand how linux identifies some devices. The names are unfamiliar to me. Even with the soundcard in my other desktop it gives it a name that I don't know. It took me ages to figure out what it was doing as I do have a separate pci soundcard on that machine and i have disabled the onboard sound in the bios. Anyway I think I have the right info to install ubuntustudio as a distro upgrade on the other desktop rather than battle on this machine.
Anyway I am glad to hear that Jack is working for so many people and Linux's multimedia apps as I will persist in getting the job done.

The main strengths of the jack system are the possibility to get really
low latencies and very flexible routing. If you don't have high

ubuntustudio on my other machine as it has the better soundcard (well not
soundonboard) and more ram too. I just don't know how to upgrade from a dvd
via the respositories.

Ok, as long as there is only green 0 (0) below
'Started'
and no red
numbers, everything's fine. The yellow % numbers are cpu-load. It
shouldn't be at 70% but rather fairly below 10%.

When getting a soundcard, make sure it is compatible. The best place to
check that is: http://alsa-project.org/main/index.php/Matrix:Main

The main strengths of the jack system are the possibility to get
really
low
latencies and very flexible routing. If you don't have high
requirements, single applications using alsa might suffice.
For loop-based and straight stuff, lmms could be a all-in-one option
(similar to fruity loops), but beware that it's still pretty early in
development and that it's not in Ubuntu Studio by default.
Try and test, find out what works for you. It could be interconnecting
apps using jack or a single app that does it for you, try, try, try,
and ask.

Carla. By the looks of it, your sound card is compatible. If you haven't
already, you need to understand what Jack is for. If you've used Re-Wire
in
the Windoze world, it's like that but better. It's used to route
("wire")
audio inputs and outputs between the music programs and the soundcard, so
it's actually your patchbay. It's also used to synchronize tempo

of
the
multiple music programs you choose.

For instance I use Ardour to record. To route inputs from the soundcard, I
go to Jack, click "connect" and connect the soundcard inputs on the
left
panel (which might appear as 'capture_1' and 'capture_2' under
'alsa_pcm' or
'system') to the tracks I created in Ardour on the right that appear
under
'ardour'. You will probably need to click on the [+] to expand and see
the
individual connections under each program you see in Jack. You simply
connect these inputs and outputs by click-dragging between them. Ardour
depends on Jack to connect all its tracks to it's master output and
bus'es
too. You disconnect by clicking on both sides of the connection and
clicking disconnect. Don't click Disconnect All unless you really mean to
Disconnect All.

So to not get confused, the "input" of the soundcard is actually an
"output"
in Jack, called

Readable Clients which makes more sense said that way. The
Writeable Clients such as your soundcard output "system or alsa_pcm",
is an
Input in Jack but a physical output respectively. Look at like the
'inputs'
to your 'outputs' and the 'outputs' of your 'inputs'.

For each Jack-aware music app (eg. Hydrogen), you'll also see them in the
Jack connections panel. To understand what Alsa is in the Linux world,
Instead of getting a driver for windows from that soundcard's website, Alsa
is the sound driver(s) for all the different sound cards our there, a
one-for-all(most actually), instead of one-for-one in the shitty windows
world. If you get any sound without Jack (ie. the startup sound), your card
is working and you really don't need to understand more about Alsa. Hope
that helps.
