(sorry, I'm on holidays and not really much on my computer) Creating ports on a sink/source is part of the session manager policy. More precisely as part of the linking policy. Sink/source/streams can operate in multiple modes: passthrough, DSP or convert. The DSP mode is when port are configured with a single channel float format and when they are visible in JACK (we could also extend JACK to show these new port types but many tools tend to crash on unexpected types). Normally Wireplumber will configure sinks/sources with their default number of channels in DSP mode. It will convert streams (firefox pulseaudio, ALSA clients,..) to the DSP mode with the number of channels of the sink they link to. This is a reasonable policy for desktop apps. If you don't use a session manager, making a Sink/Source will thus leave the node unconfigured. You have however some options to do the configuration if you don't run a session manager: 1. Use the auto port config option on streams: https://gitlab.freedesktop.org/pipewire/pipewire/-/blob/master/src/daemon/minimal.conf.in#L165 or on the sink/source https://gitlab.freedesktop.org/pipewire/pipewire/-/blob/master/src/daemon/minimal.conf.in#L306 2. Use pw-cli to send the PortConfig to the Node manually (i don't have an example handy). When I get back from holidays, I'm going to make some example config files that implement this. For linking ports, you can use any of the jack tools you probably already use (jack_matchmaker) or jack_connect. Hope this helps.
