Requires `pulseaudio pavucontrol alsa-lib alsa-utils acpilight`
Actual requirements may vary depending on your configuration. I am only writing what worked for me.
<!--more-->
Edit `config.h`
```c
#include <X11/XF86keysym.h>
/* volume keys*/
static const char *upvol[] = { "/usr/bin/pactl", "set-sink-volume", "0", "+5%", NULL };
static const char *downvol[] = { "/usr/bin/pactl", "set-sink-volume", "0", "-5%", NULL };
static const char *mutevol[] = { "/usr/bin/pactl", "set-sink-mute", "0", "toggle", NULL };
/* backlight */
static const char *brightnessup[] = { "sudo", "xbacklight", "-inc"m "5", NULL };
static const char *brightnessdown[] = { "sudo", "xbacklight", "-dec", "5", NULL };
```
Append the following lines in `static Key keys[]` array
```c
static Key keys[] = {
{ 0, XF86XK_AudioLowerVolume, spawn, {.v = downvol} },
{ 0, XF86XK_AudioMute, spawn, {.v = mutevol }},
{ 0, XF86XK_AudioRaiseVolume, spawn, {.v = upvol} },
{ 0, XF86XK_MonBrightnessUp, spawn, {.v = brightnessup} },
{ 0, XF86XK_MonBrightnessDown, spawn, {.v = brightnessdown} },
};
```
