Artix Linux Forum

I'm a new Artix user, and I migrated from Arch, which I used for a while. Now, I decided to go with S6, and all seems fine, except for one thing: I have absolutely no idea how to add services. I read the Wiki page (https://wiki.artixlinux.org/Main/S6) but I still can't figure out how to make Pipewire launch at system boot. I tried adding a script to Plasma's System Settings "Autostart" page, but that didn't work. After adding the following lines to my .bashrc, Pipewire only started when I opened a terminal and stopped when I closed the terminal.

 #!/bin/sh
 /usr/bin/pipewire & /usr/bin/pipewire-pulse & /usr/bin/wireplumber

How do I make Pipewire start on its own everytime I boot?

I used that in the file I created from a posting I seen on the wiki I think but ended up reusing the settings I used in Devuan instead.

zeus@9600k:~$ cat bin/pipewire_start.sh
#!/bin/sh
# added to start pipewire on kde login added to its autostart.

#/usr/bin/pipewire & /usr/bin/pipewire-pulse & /usr/bin/wireplumber

# kill any existing pipewire instance to restore sound
pkill -u "$USER" -fx /usr/bin/pipewire-pulse 1>/dev/null 2>&1
pkill -u "$USER" -fx /usr/bin/wireplumber 1>/dev/null 2>&1
pkill -u "$USER" -fx /usr/bin/pipewire 1>/dev/null 2>&1

/usr/bin/pipewire &

# wait for pipewire to start before attempting to start related daemons
while [ "$(pgrep -f /usr/bin/pipewire)" = "" ] ; do
   sleep 1
done

/usr/bin/wireplumber & 

/usr/bin/pipewire-pulse &

Put that in a file make it executable (chmod +x /path/to/file.sh) then go into the Autostart and add a script using that file. Log out then back in if it works anything like mine does then you will see the volume control briefly flash on the screen while it loads and activates the sound server.

While this did work, it seems to be unable to read my modified configuration in /usr/share/pipewire/pipewire.conf. The configured quantum is 124, while pw-top shows the quantum as 64. Here's my /usr/share/pipewire.conf:

# Daemon config file for PipeWire version "1.2.7" #

Is there some reason you ignore the instructions contained at the top of the file where to put the configuration file for its use?

# Copy and edit this file in /etc/pipewire for system-wide changes
# or in ~/.config/pipewire for local changes.

Put it in one of those two places and see if it does find it is the only idea I have.

The reason I placed it there is because pw-config outputs

{
  "config.path": "/home/eclipse/.config/pipewire/pipewire.conf"
}

However, copying the file to the directories you mentioned does nothing. But I will mark this thread as solved, because my original issue was solved and this is something else.
