A replacement for the deprecated padevchooser.

pasystray allows setting the default PulseAudio source/sink and moving streams on the fly between sources/sinks without restarting the client applications.

• switch default sink/source
• move playback/record stream to a different sink/source on the fly
• detect pulseaudio instances on the network with avahi
• set X property PULSE_SERVER (like padevchooser's "set default server")
• adjust volume/toggle mute of sinks/sources and playback/record streams
• rename devices (pulseaudio must have module-device-manager loaded)

To detect remote sinks/sources you need to enable module-zeroconf-discover on the local PulseAudio instance and module-zeroconf-publish on the remote side.

To control a different server than the local instance, run pasystray as:

$ PULSE_SERVER=remote_host pasystray

over status icon:

• left/right-click: open menu
• ctrl + left-click: start pavucontrol
• middle-click / alt + left-click: toggle mute default sink
• ctrl + middle-click / ctrl + alt + left-click: toggle mute default source
• scroll up/down: adjust the default sink volume
• ctrl + scroll: adjust the default source volume

over source/sink:

• scroll up/down: adjust the volume of respective stream
• left-click: set as default sink/source
• middle-click / alt + left-click: toggle mute
• right-click: open menu to rename source/sink

over playback/record stream:

• scroll up/down: adjust the volume of respective stream
• middle-click: toggle mute

If the pasystray icon is not displayed in your Unity system tray, you will have to whitelist it. Read this for instructions: http://askubuntu.com/questions/30742/how-do-i-access-and-enable-more-icons-to-be-in-the-system-tray

For Ubuntu 13.04 and above, AppIndicator is mandatory. Unfortunately, the ctrl + click / ctrl + scroll bindings don't work with AppIndicator.
