PulseAudio, previously known as Polypaudio, is a sound server for POSIX and WIN32 systems. It is a drop in replacement for the ESD sound server with much better latency, mixing/re-sampling quality and overall architecture.

This module enables PulseAudio to publish available sinks and sources via zeroconf (aka. Avahi, mdns).

The module is called module-zeroconf-publish.
