Only one of PipeWire's PulseAudio replacement server and the original PulseAudio server can run at a time.\n\n- JACK graph tools cannot show all PipeWire features, such as video ports.\n- The autogenerated API documentation is incomplete.\n- PipeWire's PulseAudio server and the original cannot run together.\n\nThe README states PipeWire is free software mostly licensed under the MIT licence, with exceptions described in the LICENSE file, so read that file before reuse or redistribution.
