# pulse-volume-monitor
`pulse-volume-monitor` is a simple C++ program that listens to PulseAudio's sink and source events and emits DBus signals `sinkChanged` and `sourceChanged` when something has been changed (volume, sink or source muted, etc).
For use with AwesomeWM in volume indicator widgets.
### Usage
`./pulse-volume-monitor dbus` or `./pulse-volume-monitor stdout` (for debugging)
### AwesomeWM Lua example
```
dbus.request_name("session", "com.ch1p.pvm")
dbus.add_match("session", "interface='com.ch1p.pvm',member='sinkChanged'")
dbus.add_match("session", "interface='com.ch1p.pvm',member='sourceChanged'")
dbus.connect_signal("com.ch1p.pvm",
function(info)
-- info.member is "sinkChanged" or "sourceChanged"
-- your code here
end
)
```
