i3wm Setting up backlight and sound

When moving to i3 window manager, my backlight and sound keys got disabled. This is a super simple fix.

Get to your i3 config in .config/i3/config, and enter these lines for the backlight:

# audio
bindsym XF86AudioRaiseVolume  exec --no-startup-id pactl -- set-sink-volume 0 +5% 
bindsym XF86AudioLowerVolume  exec --no-startup-id pactl -- set-sink-volume 0 -5%
bindsym XF86AudioMute         exec --no-startup-id pactl set-sink-mute 0 toggle

and enter in these for brightness:

bindsym XF86MonBrightnessUp exec "bash -c 'expr $(cat /sys/class/backlight/intel_backlight/brightness) + 100 | sudo tee /sys/class/backlight/intel_backlight/brightness'"
bindsym XF86MonBrightnessDown exec "bash -c 'expr $(cat /sys/class/backlight/intel_backlight/brightness) - 100 | sudo tee /sys/class/backlight/intel_backlight/brightness'"

Viola! Everything should work now :)
