Edit /usr/share/pulseaudio/alsa-mixer/paths/analog-output-speaker.conf and when the file opens find this section:

; This profile path is intended to control the speaker, let's mute headphones
; else there will be a spike when plugging in headphones
[Element Headphone]
switch = off
volume = off

Change it to this:

; This profile path is intended to control the speaker, let's mute headphones
; else there will be a spike when plugging in headphones
[Element Headphone]
switch = mute
volume = merge

Save and reboot.

Audio Function Keys

Add the following lines to ~/.xbindkeysrc

# Increase volume
"pactl set-sink-volume @DEFAULT_SINK@ +1000"
   XF86AudioRaiseVolume

# Decrease volume
"pactl set-sink-volume @DEFAULT_SINK@ -1000"
   XF86AudioLowerVolume

# Mute volume
"pactl set-sink-mute @DEFAULT_SINK@ toggle"

Screen Brightness Keys

Install the following packages:

xf86-video-intel
xbindkeys
xorg-xbacklight

Update /etc/X11/xorg-conf.d/20-video.conf:

Section "Device"
    Identifier  "Intel Graphics" 
    Driver      "intel"
    Option      "Backlight"  "intel_backlight"
    Option      "TearFree"   "true"
EndSection

Create a file in in your home directory called .xbindkeysrc and add to it:

"xbacklight -dec 5%"
    m:0x0 + c:232
    XF86MonBrightnessDown

"xbacklight -inc 5%"
    m:0x0 + c:233
    XF86MonBrightnessUp

Start xbindkeys when you start your window manager (e.g. add ‘xbindkeys’ to .xinitrc)
