edit: to avoid a "long" read... it's solved here ->

yesterday i updated ubuntu from 14-04 LTS to 16-04 LTS... (had already Kx-Studio...) .. and now my firewire light stay OFF..

(no sound... jack = OK, Bitwig plays ... ffado = hmmmm NOT OK....)

(i dunno how i done in 2014 -> the FW light was ON.)


after FFADO, for my Saffire Pro 24 i need the experimental SVN/trunk drivers.

so i would like to uninstall/remove entirely the Kx-Studio suite, as i (think) need only FFADO & JACK.

i can't remember how i installed kx-studio in last last year, so i dunno how to remove it from my system (actually i write on win10..)...

so searched there and there, posted there and too...

but Can you help me to configure my audio workstation for linux please ?

i know NOTHING about linux, its like i know 'sudo apt install libs-not-found etc...etc....

thx by advance..

Hallo Chris, I work with Ubuntu Studio and I made an Update from 14.04 to 16.04. My FFADO driver for RME-Fireface work on 14.04 very good. In 16.04 it don't work. Ubuntu 16.04 (also the base for your Kx Studio) have a Problem with FFADO. If you read the LADI- LOG Files you can can see that Ubuntu 16.04 have a Problem to assigning memory cache for FFADO.

I conact the FFADO community but i got no response. I also try to fix this problem with some Linux-profesionals but nobody could help me.

At the end I reinstalled Ubuntu 14.04. and it work.

Normaly I write nothing in englisch because my english is very bad, I hope you can undersand me. Best regards from germany.

maybe it's just my JACK config that is bad, i just changed from port audio (or alsa..) to firewire.

Hallo ChrisMK2

there is no way to downgrade Ubuntu 16.04 to 14.04.

You have to do complete new istallation of Ubuntu 14.04.

For his you lost all files of your actuall system. Please be careful if you do this. I lost a lot of files because i make a fail if I try to save my files.

Hallo ChrisMK2,

once again. Did I undersand correct. for you is FFADO an Jack important. KX-Studio is not fixed??

So, the easyest way is to use Ubuntu Studio. If you install it you have FFADO on board. If you connect your Sapire the system find it automatily.

But use 14.04.

best regards.

hello Manfred, thx for the response,

i have ubuntu studio 16-04 LTS, coz much support... (i would preferred Fedora as my bro uses it to code but he does not want to help me lol u see ? xD héhé .... so i try my self :

solved sound issues in OS/music players/youtube....

it was just amarok does not save my out settings.


just lau,nched JACK and it does not work anymore... yesterday it worked but i had some system updates available....

that also compromised my nouveau or nvidia drivers... (black screen + cursor at boot, no X launching..) ... had worked the afternoon to repair it.


do u think JACK had problem ? (its from kx studio repos)

if so, how do i repair/update it ?

edit: i think JACK has no problem, it got updated since 2010.... my FW LED is ON while there is sound..
