pw-loopback

Create loopback devices in PipeWire. More information: https://gitlab.freedesktop.org/pipewire/pipewire/-/wikis/Virtual-Devices.

  • Create a loopback device with the default loopback behavior:

pw-loopback

  • Create a loopback device that automatically connects to the speakers:

pw-loopback -m '{{[FL FR]}}' --capture-props='{{media.class=Audio/Sink}}'

  • Create a loopback device that automatically connects to the microphone:

pw-loopback -m '{{[FL FR]}}' --playback-props='{{media.class=Audio/Source}}'

  • Create a dummy loopback device that doesn't automatically connect to anything:

pw-loopback -m '{{[FL FR]}}' --capture-props='{{media.class=Audio/Sink}}' --playback-props='{{media.class=Audio/Source}}'

  • Create a loopback device that automatically connects to the speakers and swaps the left and right channels between the sink and source:

pw-loopback --capture-props='{{media.class=Audio/Sink audio.position=[FL FR]}}' --playback-props='{{audio.position=[FR FL]}}'

  • Create a loopback device that automatically connects to the microphone and swaps the left and right channels between the sink and source:

pw-loopback --capture-props='{{audio.position=[FR FL]}}' --playback-props='{{media.class=Audio/Source audio.position=[FL FR]}}'
