Echo AF12 (Firewire device) / Trisqel7.0 (given up trying)

[oNNogitaar]

Dear all,
when i bought my computer i never managed to run my soundcard(Echo Audiofire12) under Trisquel, i tried KXStudio and that worked OOTB.
Recently, because of a new grafics card, i had to update my system and my sound is not working anymore.
So i might as well try again and get it working under Trisquel...

i guess that is jack2 so must be changed to jack1
is it good to do a

Code: Select all

sudo apt-get remove -y jackd2 of libjack-jackd2 && sudo apt-get install -y jackd1 libjack0 qjackctl

Aparently Trisquel has a rt kernel available:
http://www.fsfla.org/ikiwiki/selibre/li ... e/#repo-rt
...lets hope it is better than the previous one
I have to add the following line to your sources.list: deb http://linux-libre.fsfla.org/pub/linux-libre/rt squeeze main

How can i edit that list, please?
(gk?)sudo gedit /etc/apt/sources.list(.d?)

i guess that is jack2 so must be changed to jack1

Code: Select all

sudo apt-get install jackd1

should suffice. jackd2 will be removed automatically.

How can i edit that list, please?
(gk?)sudo gedit /etc/apt/sources.list(.d?)

Code: Select all

gksudo gedit /etc/apt/sources.list

And you add the line.

You can also create a new file in /etc/apt/sources.list.d and call it, for example, trisquel_rt.list

Code: Select all

gksudo gedit /etc/apt/sources.list.d/trisquel_rt.list

It is equivalent. The second option is just a little bit cleaner.

Anyway, you have to

Code: Select all

sudo apt-get update

whenever you modify your software sources and before trying to install the new package(s).

Thank you! Pablo
I did a:

Code: Select all

sudo apt-get install jackd1

It returned:

Code: Select all

no talloc stackframe at ../source3/param/loadparm.c:4864, leaking memory
...
The following packages were automatically installed and are no longer required:
  hal-info libdbusmenu-qt5 libqt5clucene5 libqt5help5 libqt5svg5
  libqt5xmlpatterns5 libqtscript4-core libqtscript4-gui libqtscript4-network
  libqtscript4-uitools libqtscript4-xml linux-image-3.13.0-43-generic
  linux-image-3.2.0-54-generic linux-image-extra-3.13.0-43-generic
  musescore-soundfont-gm python-pycurl
Use 'apt-get autoremove' to remove them.

The following extra packages will be installed:
  jackd1-firewire libjack0 libzita-alsa-pcmi0 libzita-resampler1

The following packages will be REMOVED:
  jackd2 jackd2-firewire libjack-jackd2-0
The following NEW packages will be installed:
  jackd1 jackd1-firewire libjack0 libzita-alsa-pcmi0 libzita-resampler1
...

Is that allright? It does not say it installed qjackctl... probably still there?

Code: Select all

jackd -V

outputs:

Code: Select all

jackd version 0.124.2 tmpdir /dev/shm protocol 25

Do you recomment doing the?:

Code: Select all

apt-get autoremove

If i understand correctly, the system uses /etc/apt/sources.list and all the files in /etc/apt/sources.list.d as sources, right? (http://manpages.debian.org/cgi-bin/man. ... &locale=en)
I decided on the cleaner option so to create /etc/apt/sources.list.d/trisquel_rt.list
How can i do that, please? (need admin rights)

in sources.list.d i found 2 files for non free software:
kxstudio-non-free.list
kxstudio-non-free.list.save
Can i delete those?

Thank you!!

[oNNogitaar]

noone?

[oNNogitaar]

I did a:

Code: Select all

sudo nautilus

and created /etc/apt/sources.list.d/trisquel_rt.list
and wrote in the line: deb http://linux-libre.fsfla.org/pub/linux-libre/rt squeeze main

What should i do to install the realtimekernel?

Code: Select all

sudo apt-get update
sudo apt-get install kernelname(?)

(how do i know its name?)
i do not have to add a repository, right?

any ideas about my other questions, please?
Thank you!

[oNNogitaar]

i gave this up.
Thanks for the help Pablo!
