camilladsp camillagui as user services Fedora 40

[atomant]

Hi,

I tested the github service scripts available on github and they didn't work

~$ journalctl --user-unit=camilladsp
sep 26 13:16:46 systemd[3507]: /etc/xdg/systemd/user/camilladsp.service:12: Standard output type syslog is obsolete, automatically updating to journal.>
sep 26 13:16:46 systemd[3507]: /etc/xdg/systemd/user/camilladsp.service:13: Standard output type syslog is obsolete, automatically updating to journal.>

sep 26 13:16:46 systemd[3507]: camilladsp.service: Failed with result 'exit-code'.

Therefore, here is my little contribution:

sudo nano /etc/systemd/user/camilladsp.service

[Unit]
Description=CamillaDSP Service
After=network.target

[Service]
ExecStart=/usr/local/bin/camilladsp /home/user/.config/.camilladsp/stereo.yml -p1234 -w -o /home/user/.config/.camilladsp/camilladsp.log -s /home/user/.config/.camilladsp/statefile.yml
Restart=always

[Install]
WantedBy=multi-user.target

sudo nano /etc/systemd/user/camillagui.service

[Unit]
Description=CamillaDSP Backend and GUI
After=multi-user.target

[Service]
Type=idle
ExecStart=/usr/bin/python3 /opt/camillagui/main.py

[Install]
WantedBy=multi-user.target

To install, run and enable:
sudo systemctl --user daemon-reload
sudo systemctl --user start camillagui camilladsp
sudo systemctl --user status camillagui camilladsp
sudo systemctl --user enable camillagui camilladsp
sudo systemctl --user daemon-reload

To check for errors:
journalctl --user-unit=camilladsp --user-unit=camillagui

UPDATE sept 27

If it doesn't start at boot, check again with:
sudo systemctl --user status camillagui camilladsp
journalctl --user-unit=camilladsp --user-unit=camillagui


sudo systemctl --user disable camillagui camilladsp

Then edit the files, and again:
sudo systemctl --user daemon-reload
sudo systemctl --user start camillagui camilladsp
sudo systemctl --user status camillagui camilladsp
sudo systemctl --user enable camillagui camilladsp
sudo systemctl --user daemon-reload

and reboot to test...

New files:

~$ cat /etc/systemd/user/camilladsp.service

sudo nano /etc/systemd/user/camilladsp.service

Should "user" be the user name?

Would "~/..." or "$HOME/..." work in place of "home/user/..."?

 

[atomant]

Should "user" be the user name?

If your files are in ~/.config then yes. Adjust for your proper paths.

Would "~/..." or "$HOME/..." work in place of "home/user/..."?

Not tested. I'm not a systemd specialist. I worked 20 years with rc.d. Still learning.

BTW I made a few changes again as services were not initializing properly. They goes like this:

1- In the service files:
After=graphical.target
instead of
After=pipewire.socket network.target
2- I still was not satisfied so I made an autostart and disabled the services:

sudo systemctl --user disable camillagui camilladsp

$ nano .config/autostart/fixsound.desktop
[Desktop Entry]
Type=Application
Exec=bin/fixsound.sh
X-GNOME-Autostart-enabled=true
NoDisplay=false
Hidden=false
Name[en_CA]=fixsound
Comment[en_CA]=Fix alsamixer master playback sound and start camilladsp
X-GNOME-Autostart-Delay=10
Name[fr_CA]=fixsound

$ nano  bin/fixsound.sh
#!/bin/bash
systemctl --user restart camilladsp camillagui
amixer -c 2 set Master playback 27 || amixer -c 1 set Master playback 27 || amixer -c 0 set Master playback 27

Again, adjust fou your paths.

You might not need that if the services are loading properly. It was not the case here.
Also if your sound volume is ok, you don't need the 'amixer' line. I need it because wirelumber/pipewire is resetting the sound card volume to 37%

Determine the card number with 'aplay -l'. Mine changes from 1 to 2 randomly at boot.

Would "~/..." or "$HOME/..." work in place of "home/user/..."?

It is possible for user services.

Mine changes from 1 to 2 randomly at boot.

It's possible to ensure the order remains the same across reboots with USB devices (I've not tried it with on board devices).

It's also worth looking at the alsa-capabilities script (mention on the link below) - I find it easier to interpret the output (instead of aplay).

Hi, thanks for your interest.
It's also possible. I read on that not so long ago.
I've been very busy for the last 6 weeks, fixing one issue after another. Priorities. Will be included eventually. For the moment I test the most probable interface and if it returns an error, I test the next one. Crude but working until I configure it properly.
