I3wm audio problem

Hi, Im having a problem to control volume with i3wm,(the problem was i deleted the config file and replace with my old one so probably thats why)

i tried both of this it didnt work:
#Volume Control
bindsym $mod+F11 exec amixer set Master 5%-
bindsym $mod+F12 exec amixer set Master 5%+
bindsym XF86AudioRaiseVolume exec --no-startup-id pactl set-sink-volume 1 +5% #increase sound volume
bindsym XF86AudioLowerVolume exec --no-startup-id pactl set-sink-volume 1 -5% #decrease sound volume

Thank you for you attention :slight_smile:
