How to disable audio devices with Pipewire

wireplumber.md

Find your devices

$ pactl list short

Create the Wireplumber rule to disable the device

$ mkdir -p $HOME/.config/wireplumber/main.lua.d
$ vi $HOME/.config/wireplumber/main.lua.d/51-disable-devices.lua
$ systemctl --user restart wireplumber

Tested on Fedora 38 with Wireplumber 0.4.14 and Pipewire 0.3.70

zz-disable-devices.lua

rule = {
  matches = {
    {
      { "device.name", "equals", "alsa_card.usb-046d_HD_Pro_Webcam_C920_44FFD86F-02" },
    },
    {
      { "device.name", "equals", "alsa_card.pci-0000_01_00.1" },
    },
  },
  apply_properties = {
    ["device.disabled"] = true,
  },
}

table.insert(alsa_monitor.rules,rule)

For Wireplumber 0.5+, use the following instead:

<yourEditor> $HOME/.config/wireplumber/wireplumber.conf.d/51-disable-devices.conf

monitor.alsa.rules = [
  {
    matches = [
      {
        device.name = "~alsa_card.pci-*"
      },
      {
        device.name = "alsa_card.usb-Sony_Interactive_Entertainment_DualSense_Wireless_Controller-00"
      }
    ]
    actions = {
      update-props = {
      	device.disabled = true
      }
    }
  }
]
