Input table

Variable	Meaning	Type	Default
timeout	Refresh timeout seconds	int	5
settings	User settings	function	empty function
width	Bar width	int	63
height	Bar height	int	1
ticks	Set bar ticks on	boolean	false

togglechannel	Toggle channel	string	nil
colors	Bar colors	table	see Default colors
notification_preset	Notifications settings	table	naughty.config.defaults

cmd is useful if you need to pass additional arguments to amixer. For instance, you may want to define command = "amixer -c X" in order to set amixer with card X.

In case mute toggling can't be mapped to master channel (this happens, for instance, when you are using an HDMI output), define togglechannel as your S/PDIF device. Read alsa page to know how.

settings can use the following variables:

Variable	Meaning	Type	Values
volume_now.level	Volume level	int	0-100
volume_now.status	Device status	string	"on", "off"

In multiple screen setups, the default behaviour is to show a visual notification pop-up window on the first screen. By setting followtag to true it will be shown on the currently focused tag screen.

Buttons

If you want buttons, just add the following after your widget in rc.lua.

volume.bar:buttons(awful.util.table.join (
          awful.button({}, 1, function() -- left click
            awful.spawn(string.format("%s -e alsamixer", terminal))
          end),
          awful.button({}, 2, function() -- middle click
            awful.spawn(string.format("%s set %s 100%%", volume.cmd, volume.channel))
            volume.update()
          end),
          awful.button({}, 3, function() -- right click
            awful.spawn(string.format("%s set %s toggle", volume.cmd, volume.togglechannel or volume.channel))
            volume.update()
          end),
          awful.button({}, 4, function() -- scroll up
            awful.spawn(string.format("%s set %s 1%%+", volume.cmd, volume.channel))
            volume.update()
          end),
          awful.button({}, 5, function() -- scroll down
