Tested with PipeWire 0.3.26. The implementation is quite basic and simple, yet it surpasses the JACK one in terms of features. For example, support for the most common surround mappings is provided. As opposed to JACK, an option to disable the auto endpoint connection is not provided. However, it's something that can be easily implemented if needed. Support for echo cancellation will definitely be added in future.
