### Pulse or ALSA only
Try running this command:
```amixer -D pulse sget Master```
If that prints something like this, then the default setting of 'pulse' is probably fine:
```
Simple mixer control 'Master',0
Capabilities: pvolume pvolume-joined pswitch pswitch-joined
Playback channels: Mono
Limits: Playback 0 - 64
Mono: Playback 64 [100%] [0.00dB] [on]
```
If it prints something like this:
```
$ amixer -D pulse sget Master
ALSA lib pulse.c:243:(pulse_connect) PulseAudio: Unable to connect: Connection refused
amixer: Mixer attach pulse error: Connection refused
```
then try setting the environment variable `AWW_VOLUME_CONTROLLER` to `alsa_only`.
## Control volume
To mute/unmute click on the widget. To increase/decrease volume scroll up or down when mouse cursor is over the widget.
