Fedora, switch audio channels with pipewire and wireplumber 0.5

· One min read

Update on this post, with the update to wireplumber v0.5 lua configuration files are not supported anymore. To switch channels on v0.5 you have to create the following file

.config/wireplumber/wireplumber.conf.d/51-change-channels.conf
monitor.alsa.rules = [
  {
    matches = [
      {
        node.name = "<name of the node>"
      }
    ]
    actions = {
      update-props = {
        audio.position = "FR,FL"
      }
    }
  }
]

Check the previous post to understand how to retrieve the name of the node, if needed.

warning

The lua configuration files are valid only for wireplumber v<0.5. Please check here for the configuration required on v=0.5. This post remains valid for what concerns retrieving the node name required in the config file.

I bought a pair Creative Pebble V3 and given my desk setup and the cables of the 2 speakers, I needed to switch left and right audio channels in order to setup correctly the speakers.

Now, I'm running Fedora Workstation and I never had to troubleshoot, manage, or change any audio settings besides adjusting volume when needed. I found out this task is not as easy as it seems, probably for a mixture of lack of documentation and lack of skills on my side.
