This exposes the actual devices (and virtual sinks/sources) as reported by PulseAudio to an application, allowing it to select the devices itself and, for example, record from (or render to) two devices at the same time. The "PulseAudio" device (which is movable) is still the default, as before, with the same GUID to preserve compatibility with existing setups.
Based on a patch by Mark Harmstone mark@harmstone.com, with changes by Sebastian Lackner sebastian@fds-team.de.
