Wireplumber 0.5 disable alsa devices and pro-audio

Looks like I had some oldies lying around on the disk as wireplumber greeted me with

wireplumber: Old configuration file detected: /home/muh_user/.config/wireplumber/main.lua.d/51-disaa-paskaa.lua
wireplumber: Old configuration file detected: /home/muh_user/.config/wireplumber/main.lua.d/52-alsa-bufferit.lua

Luckily there's a good guide for migrating unsupported lua-scripts to new spa-json files at Freedesktop.org - wireplumber migration and after some new bracketing and cleanup.

Disable devices

~/.config/wireplumber/wireplumber.conf.d/51-disaa-paskaa.conf disables bunch devices like webcam audio, nvidia hdmi audio etc. wpctl status and wpctl inspect <id> to get device.name.

monitor.alsa.rules = [
  { 
    matches = [ 
      { "device.name" = "alsa_card.pci-0000_01_00.1" },
      { "device.name" = "alsa_card.usb-046d_Logitech_Webcam_C925e_16FE83DF-02" },
      { "device.name" = "alsa_card.pci-0000_00_1f.3" } 
    ]
    actions = {
      update-props = {
        device.disabled = true
      }
    }
  }
]

And another to set pro-audio profile for my usb interface, probably most of the settings are just for show except device.profile.

monitor.alsa.rules = [
{ 
  matches = [ { "device.name" =  "alsa_card.usb-Solid_State_Logic_SSL_2_-00" } ]
  actions = {
    update-props = {
      api.alsa.period-num = 2,
      api.alsa.period-size = 64,
      api.alsa.headroom = 0,
      api.alsa.disable-batch = true,
      device.profile = "pro-audio",
    } 
  }
}

For the very best #yotld moments. Have a great day!
