pavucontrol 0.9.4-2 (amd64 binary) in ubuntu hardy

 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.
 .
 PulseAudio Volume Control (pavucontrol) is a simple GTK based volume
 control tool (mixer) for the PulseAudio sound server. In contrast to
 classic mixer tools this one allows you to control both the volume of
 hardware devices and of each playback stream separately. It also allows
 you to redirect a playback stream to another output device without
 interrupting playback.
