TC Electronic Konnect 24D

Postby krussedull » Tue Aug 20, 2019 7:56 pm

Hello guys!

I'm having some problems getting my TC Electronic Konnekt 24D (firewire card) working in the Ubuntu Studio distro.
About 1 year ago I got it working on another partition (with Linux Mint 19) after spending like 2 days "hacking".
..but ofc I've forgotten it all now, and I'm stuck again after a day of frustration reading this and other forums like a mad man.

The problem is that QjackCtl won't start in "firewire" mode (errors below) and the "alsa" mode just gives crap sound.
I'm an experienced Linux user that am trying to switch from an Ableton/Windows stack to BitWig/Linux

OK, so here are some details from my system:

Have you tried removing the "snd-dice" module? Is it loaded?

Today I did some more research and like you said, this is something I missed!
Doing this will load jack initially, however after some time (see log) the audio drops out with an error.

Unloading snd-dice and rebooting:

Code: Select all

alf@studio:~$ cat /etc/modprobe.d/blacklist-snd-dice.conf
# https://sourceforge.net/p/ffado/mailman/message/35041472/
# http://mailman.alsa-project.org/pipermail/alsa-devel/2014-September/081731.html
# https://linuxmusicians.com/viewtopic.php?p=83553
blacklist snd-dice
blacklist snd-firewire-digi00x
blacklist snd-firewire-tascam
blacklist snd-firewire-lib
blacklist snd-firewire-transceiver
blacklist snd-fireface
blacklist snd-firewire-motu

(I also tried only with the snd-dice, same result)

Initial jack load:

To me it seems like some process has "captured" jack or something, stopping it from successfully start again.
But Im only guessing..

Code: Select all

alf@studio:~$ ps aux |grep -i jack

So I guess I'm still stuck :?

Any news? I have a trusty old TC StudioKonnekt 48 I’d love to get working under Linux. My issues are similar- constant dropouts/stuttering, can’t get below 256 sample buffer. Ubuntu 18.04 with low-latency kernel here.

Nothing new I'm afraid. Was thinking to take this case further with the ffado community, but already spend some time on this, so right now I'm gonna have to throw in the towel and work in Windows 10 until I get this working.

I managed to get the StudioKonnekt working by blacklisting the ALSA drivers and using the Firewire drivers. Stuck at 48/44.1 kHz, but it seems to be working well so far.

I gave it another try and also got it working!

1) I ditched Ubuntu Studio and installed Linux Mint 19.2 (my favorite distro anyway) and did it from scratch

2) Installed the kxstudio repos
https://kx.studio/Repositories

3) Installed these drivers

Code: Select all

sudo apt install jackd2 jackd2-firewire pulseaudio-module-jack libffado2


4) Disabled some modules

Code: Select all

sudo vim /etc/modprobe.d/blacklist-snd.conf


Added this:

Code: Select all

# http://mailman.alsa-project.org/pipermail/alsa-devel/2014-September/081731.html
# https://linuxmusicians.com/viewtopic.php?p=83553
blacklist snd-dice
blacklist snd-firewire-digi00x
blacklist snd-firewire-tascam
blacklist snd-firewire-lib
blacklist snd-firewire-transceiver
blacklist snd-fireface
blacklist snd-firewire-motu


5) Installed and used Cadence (from the kxstudio repos) to start/configure jack

Code: Select all

sudo apt install cadence


6) Installed the linux low-latency driver

Code: Select all

sudo apt install linux-lowlatency


7) Added myself to the audio group:

Code: Select all

sudo usermod -a -G audio `howami`


8) BONUS! Installed linvst and got lots of windows vst working :)
