Cadence: JACK is set to NOT auto-start on login

Cadence has worked great for years but yesterday when I started cadence, all settings were greyed out.
I have made no changes to the system [ archlinux] other than apply updates.

I've tried:

Code: Select all

cadence-session-start --maybe-system-start
JACK is set to NOT auto-start on login
Tried:

Code: Select all

cadence-session-start -s
JACK Started Successfully

ps ax | grep [j]ack
  28839 ?        SLsl   0:00 /usr/bin/jackdbus auto
But cadence screen is still greyed out.

Any ideas?

That's telling you jackdbus isn't available. On Arch jack2 and jack2dbus have been split up, re-combined, split up again ... how the two are packaged has changed more than once while I've been using Arch.

First thing -- do you have jackdbus installed?

Code: Select all

$ pacman -Q|grep jack

Ok - I've gotten jack to load and work, however Cadence is still Grayed Out and not configurable.

my ~/.xinitrc starts Cadence

Code: Select all

cadence-session-start --maybe-system-start &
~/.config/jack/config

Code: Select all

I used Cadence in the past. If there was a problem cadence-session-start --reset usually fixed it. I also deleted the config file at times.

You could try commenting out the .xinitrc entry and just type 'cadence' into a terminal.

Hi merlyn.

I have tried both of your suggestion and it does not resolve the Grayed out issue.

I created a test account and cadence work fine under it, so there is something under my user account that is messed up.
I've tried:
deleting ~/.config/Cadence
deleting ~/.config/jack
deleting ~/.config/.asound
deleting ~/.config/falkTX

As stated above I have cadence running and the sound is working but everything under cadence is grayed out and I am unable to reconfigure it, which is needed since I use both alsa and firewire.

Thanks for your suggestions.

Strange. Have you tried re-installing Cadence?

Is Cadence somehow running as root? That would explain why jackdbus is running but Cadence can't see it.

Is your user in the realtime group? I wouldn't have thought that would grey out Cadence but it does seem to be something related to your user account.

I have not tried reinstalling cadence.
I know that it is related to the user account because I created a test account and it runs fine under it.
I have tried removing the following and allowing jack and cadence to recreate them:

Code: Select all

~/.config/Cadence
~/.config/jack
~/.config/falkTX
~/.asoundrc
I don't see how cadence could be running as root. It is being launched from ~/.xinitrc

Code: Select all

cadence-session-start --maybe-system-start &
My user is in the audio & realtime groups.

You could try cadence-git from the AUR :

Cadence as suddenly decided to work.
The screen is no longer grayed out and I can make changes to the configuration.

I have no idea what made it start working.
All I've done to my system is install 2 packages and apply updates and I really don't think that had anything to do with it. I still believe it was a user account issue.

The packages I installed were a couple of python packages:

Code: Select all

python-pyxdg-0.27-1
