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 is a simple gtk tool which registers an icon in the tray area and allows quick access to some features of the pulseaudio sound server. specifically it can do for you:
* notify about new sink/sources becoming available on the lan
* quickly change the default pulseaudio sink/source/server assigned to
the current x11 display, selecting devices available on the lan
* start the auxiliary tools pulseaudio volume control, pulseaudio volume
meter, pulseaudio manager, pulseaudio preferences
