pulseaudio-module-udev 1:0.9.19-0ubuntu1 (i386 binary) in ubuntu karmic

 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 detect new sound devices dynamically via
 the udev API.
 .
 The module is called module-udev-detect.
