|
- Create a loopback device with the default loopback behavior:
|
|
|
|
|
|
|
|
|
|
`pw-loopback`
|
|
|
|
|
|

|
|
|
- Create a loopback device that automatically connects to the speakers:

|
|
|
|
2021-11-23 02:48:50 +00:00
|
|
|
`pw-loopback -m '{{[FL FR]}}' --capture-props='{{media.class=Audio/Sink}}'`

|
- Create a loopback device that automatically connects to the microphone:
|
2021-09-05 15:44:42 +01:00
|
|
|
|
2021-11-23 02:48:50 +00:00
|
|
|
`pw-loopback -m '{{[FL FR]}}' --playback-props='{{media.class=Audio/Source}}'`
|
2021-09-05 15:44:42 +01:00
|
|
|
|
2021-11-23 02:48:50 +00:00
|
|
|
- Create a dummy loopback device that doesn't automatically connect to anything:
|

|
|
|
|
2021-11-23 02:48:50 +00:00
|
|
|
`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]}}'`
|
