Glossary
Device
Devices are controlled by a single driver (usually alsa), which exposes "active routes" i.e. which sources/sinks are active on the device right now. For each active route, the session manager creates and maintains a route. In Sonusmix devices usually refer to any hardware source or sink.
Endpoint
A collection of nodes that serves as either a source or sink of data, audio, or other signals. In the context of Sonusmix, an endpoint refers to all sorts of places where media can come from or go to.
