No sound at all

I have re-booted but it makes no difference. Can you telle me where I switch between Out1/Out2 and Out3/Out4 ?

I was thinking about my Behringer which has 4 channels. So no, that wouldn't work.

If you recently installed AVLinux, there is a new step - PulseAudio.

So re-boot, open Qjackqtl but don't start it yet, on the right side of Qjackqtl open Setup..., the left tab under Settings says Parameters so open that and choose "alsa" as the driver and you want the Realtime box below it to show the green check, to the right I'd use Sample Rate at 48000 and Frames/Period 512. Then, still under Settings, open the right tab Advanced. The only two items under Advanced I'd change (if needed) are Output Device: (I chose hw:U192k) and Input Device: (I chose hw:U192k) - both were blank before chose them. Then choose Cancel to get back to Qjackqtl and turn Start by clicking in the upper left.

Next, under Applications > MultiMedia > Hardware Configuration > PulseAudio Volume, make sure things are good for your speakers.

Then, open Mixbus. If you have a choice, you may want to choose to follow jack (it should show red text). If not, make sure you can choose between 2 (card) and 3 (usb).

See if that works.

And while I was typing, MMM put it in more succinct language. But I did like PulseAudio :-)

PA shouldn't be an issue in AVLinux as Glenn has made sure qjackctl runs start/stop scripts which establish/release a PA <--> Jack bridge, which shares the device between Jack and ALSA-only devices. Very nice. There's a good summary about PA/Jack here:
https://wiki.archlinux.org/index.php/Pul...rough_JACK
Also, if you decide to include a2jmidid -e into your script, you should set "MIDI driver" to "none" and under "Misc" untick "Enable ALSA Sequencer support" - that way you have only a single MIDI tab containing all devices in the connections window.

MMM
P.S.: back to the OP: of course you can make your actual sound device the default ALSA device and when qjackctl is set to "default" Bob's your uncle...

Thanks, that did it! Great. How could I forget my soundcard in the Qjackctl setup, - sometimes I amaze myself

All the best.

By monitor section you mean the top of the strips? Here at the top of the master strip I can toggle between "EQ, comp, fader" and "VCA, Out, Comments". At "Out" it says "1/2", and I can choose between "Disconnect", "Out: 1+2" and "Routing Grid".

I quit Mixbus and Qjackctl, then re-started Mixbus after starting Carla, but I see no connections in Carla, and then suddenly the Carla window disappears. I started it again but soon after it disappeared again. I don't have Patchage or Catia, but will they be much different from Qjackctl and Carla?

About your laptop, I would have slammed that bloody mute key with a hammer lol

I am in the middle of a recording session .

add Carla after Jack is running
it will show you clearer what is connected to waht and allowes you to reconnect
I think what goes to system should go to pulse

sorry i am too busy nw
