Jack and Carla?

Postby LinMusGuy » Wed Jun 19, 2019 8:37 am

Strangely today suddenly Carla no longer connects to Jack, and Jack looks upset:

What happened?

Did you upgrade anything? What distro are you using? Do you usually start jack via Qjackctl? Try starting Jack this way:

Code: Select all

jackd -d alsa --device hw:0

Or if you have two sound cars the same command with hw:1 instead of hw:0.

Could be - I had a series of upgrades from the KXStudio repositories.

What distro are you using?


Linux Mint 17

Yes.

Try starting Jack this way:

Code: Select all

jackd -d alsa --device hw:0



Now Carla works again. :D

But the GUI of QjackCtl is still out of order.

Maybe there are system lib/app mis-matches, as mint 17 is good, but old.
If you have an external drive for test setups, installing a current release of Mint
could be a more stable use of the Kx repos.
I have a Mint 18 that is very stable, although aging fast :( :wink:
Cheers

Well - Jack started one time, but no more. Now I get:

Code: Select all

Maybe I should indeed upgrade my Linux version?

This is really weird. I'm on Mint 17.1 too, updated KXStudio and I'm on latest QJackctl and latest jackd2 package. If it's not too much trouble (which I think it is) then you might want to consider re-instelling Linux. Are you sure it's not a broken or "almost broken" hard disk? I'd backup my files asap if I were you.

Good luck! :)

I have made a back-up of my personal files (those are the most important), so that worry is out of the way. :)

Code: Select all

 sudo usermod -a -G audio USERNAME

This helped me to get Jack working again, but I still get the deformed GUI of QjackCtl.

Solved! I could resize the GUI by putting the cursor on the borders and dragging them to their normal position by means of the ->| signs on the screen. How simple can it be! :mrgreen:
