pulseaudio-esound-compat 1:4.0-0ubuntu6 (amd64 binary) in ubuntu saucy

 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 package contains the ESD compatibility components used by some
 older versions of complete desktop environments, e.g., GNOME, and
 many useful applications. It enables a PulseAudio sound server to
 fully replace ESD.
