# Volume widget
|
||||
|
||||
Simple and easy-to-install widget for Awesome Window Manager which represents the sound level: 
|
||||
|
||||
Note that widget uses the Arc icon theme, so it should be [installed](https://github.com/horst3180/arc-icon-theme#installation) first under **/usr/share/icons/Arc/** folder.
|
||||
|
||||
## Customization
|
||||
|
||||
It is possible to customize widget by providing a table with all or some of the following config parameters:
|
||||
|
||||
| Name | Default | Description |
|
||||
|---|---|---|
|
||||
| `volume_audio_controller` | `pulse` | audio device |
|
||||
|
||||
## Installation
|
||||
|
||||
- clone/copy **volume.lua** file;
