Fresh install xubuntu 18.04 dit the gcc5 and kx studio debs installed cadence,carla and musicscore.
start cadence see server status "stopped" so press start then failed to start jack check the logs ,yeah great where are the logs ?
Rotten google give all crap not what you ask,or info form years back but ok that's google .More surprised that it not works, the old kxstudio installed and just run. All this grumpy person can say FALK please come back soon.Make a iso that just run again .

In Cadence go to the 'Tools' tab and click on 'Logs' to see JACK and A2J logs.

don't forget to install kxstudio-default-settings

@rghvdberg that was a good one dit that rebooted.
@ never see that and using kx for years.

Housten i have a problem.

We could do with a bit more info. Is it hw:0 you want to use?

Quite often it's pulseaudio so try if you don't have that already.

It was most likely installed on your system though. If you don't install it you will need to manually set up your system for realtime use.
It looks like you don't have the right card selected in cadence's settings.

Deleted due to irrelevancy, thanks for clearing out my brain fog merlyn.

I think you want to start Jack. Maybe Jack started for the wrong audio device. We musicians/music producers usually have an external USB audio device. Maybe the following works.

1. Determine audio card "number" w/ the command: 2. Start Jack, for example, for your second audio device (number 1). The first audio device (number 0) is usually the on-board audio card which you do not want to use.

pulseaudio-module-jack was installed. so next
cat /proc/asound/cards
0 [HDMI ]: HDA-Intel - HDA Intel HDMI
HDA Intel HDMI at 0xc1310000 irq 52
1 [Loopback ]: Loopback - Loopback
Loopback 1
2 [PCH ]: HDA-Intel - HDA Intel PCH
HDA Intel PCH at 0xc1314000 irq 49 so i assumed i need 2 as no hdmi connected dit
jackd -d alsa --device hw:2 resulted in

Before the cntr c i try cadence that say stopped .So in a moment i remembered Linuxmusisian1 hint and go to cadence configure and changed to hw:0 to hw:2
And it started Happy me.

TY all for the hints and info.:")

Glad you got it working.
