pw-loopback

Create loopback devices in PipeWire. More information: https://docs.pipewire.org/page_man_pw-loopback_1.html.

• Create a loopback device with the default loopback behavior:

pw-loopback

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

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

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

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

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

pw-loopback {{[-m|--channel-map]}} '{{[FL FR]}}' {{[-i|--capture-props]}} '{{media.class=Audio/Sink}}' {{[-o|--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 {{[-i|--capture-props]}} '{{media.class=Audio/Sink audio.position=[FL FR]}}' {{[-o|--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 {{[-i|--capture-props]}} '{{audio.position=[FR FL]}}' {{[-o|--playback-props]}} '{{media.class=Audio/Source audio.position=[FL FR]}}'
