This config above maps the channels of an external audio interface (Focusrite Scarlett 2i2) to separate virtual mono devices.
The config can be placed in
/etc/pipewire/pipewire.conf.d/10-i2i.conffor example. Afterwards you need to reload PipeWire, e.g.systemctl --user restart pipewire.service.More details and examples can be found in the PipeWire documentation:
