Hi Edu,
I did not know that there's gtk graphical support for screen-readers
these days. and that thay're good enough to even work wit complex
applications such as ardour. Wow, That's amazing.
If you like the console:
http://ltsb.sourceforge.net/ is a "guide is inteded for blind, tuxish
musicians and all others, who simply like the console." It may be a bit
outdated though.
As for your sound-issue: It _may_ be pulseaudio blocking the card.
Edit /etc/pulse/client.conf or $HOME/.pules/client.conf and set
autospawn = no
and simply stick to use JACK.
jackd requires exclusive access to the soundcard. So if the system is
playing sound (I guess your voice-speak accessibility system) JACK can
not use that card.
If the text-to-voice application supports JACK you could launch jackd
before that, but you're probably better off using the built-in soundcard
for that and use jack only for for audio-engineering.
It looks like your main problem boils down to wrong numbering of the
sound-cards. This has been a long standing issue on Linux and there are
a few ways around it:
1) If the numbering is consistent on each boot: you can simply not care
about the number and configure all audio-software to use whatever ID.
2) the "modern way" using udev:
http://alsa.opensrc.org/index.php/Udev
3) the "old way" using module load options:

It may also help to split up your many questions into several emails to
get better answers. eg. sound-card numbering, jackd startup from the
console, and last but not least: recommended applications for whatever
audio task you're up to.
You may also find a lot of answers to those already via google or the
archive of this list.
best,
robin
PS. As far as I know, you are not the only Linux-Audio-User on this list
who needs to rely on a screen-reader. Others may be on holiday or are
just busy.
PPS. I have top-posted because I assumed that's easier for both
screen-readers and text-to-speech synths.
The preferred method on this list is to use inline-replys or
bottom-posting. I've wondered a few times if this is a problem with
accessibility in general. Care to enlighten me?

Hello guys, peace and music to all of you.
Here's my story:
I won a laptop some months ago, and with the Windows 7's arrival I
decided to try a Linux distro, more precisely Ubuntu, for its facility
and also, for the Gnome's accessibility from the CD boot to the final
instalation, which is an enormous advantage for us blind users, when we
want to setup a computer independently. I use computer for ten years and
it's good to see Linux and Apple's developers going towards facilities
to everybody... I've mentioned Apple because seems that Apple's
Voiceover can also be accessed even during the instalation according to
an article I've read on the web.
Anyway, I've tested Ubuntu 9.10 and it wasn't that good because it had
some audio issues including with the Orca's usage, so I decided to wait,
and soon came Ubuntu 10.04 and, for the moment, it took all the chances
of Windows getting wrapped into my laptop. Besides, with a few, very few
programs I can do all the things I need to do... Of course things may
change in the future, but it's good to work in a system so light,
secure, and it's even better to find a supportive comunity.
Last saturday I decided to move my desktop computer, an Athlon X2 4000,
Asus M2N-SLI, 2GB of RAM with two hard disks, to Ubuntu 10.04.1 64bits
version. I really got amazed with the performance, even the Orca screen
reader is more responsive with the 64bits version. I'm interested in
audio production using Linux, so I need clues.
I have two audio cards, the mother board's built-in and the Delta
Audiophile 2496, the ladder one detected as card 0, wich according to my
understanding is the default card. But I was unable to get output from
the Delta, so I had to select the built-in sound card as my default
output for the moment. Then, after further reading I could install jackd
and Ardour for a test, and with Ardour I get all the feedback I need
while playing sounds through Delta. But of course, my goall is to make
the system work fully with the Delta.
What should I do to build a stable audio set using Ubuntu? And of
course, what are the must have programs? Since Orca is GTK-based, I'd
prefer to stay far from KDE due to accessibility issues. The thing I've
loved about Ardour is that I'm able to control jack without having to
access the jack GUI, which is KDE. But of course, if I can adjust
settings by editing configuration files it'll be better.
Any tips on how to make things work decently will be very appreciated.
Sorry for some obvious questions that I might have asked, and sorry for
the book.
Thanks in advance for all the input.
Warm regards from São Paulo, Brazil.
Edu Camargo.
