After upgrading from PulseAudio to PipeWire my sound devices now feature the "Pro Audio" profile however I've Googled for it and haven't found anything interesting. You can find it by running
PulseAudio Volume Control and see it under the Configuration tab for your devices.
Would be nice if someone could, I don't know, glance over PipeWire sources (I'm not a C programmer per se and I don't really understand digital audio aside from the very basics) and explain what it is and why the user may want to use it instead of e.g. something which is offered by default.
