    Just wanted to make a thread to help make it easier to find this information. Tested with Toughbook CF-31 MK2, may work with other models.

    Touchpad Fix
    1) Open Terminal
    2) sudo gedit /etc/default/grub
    3) In the grub file,
    CHANGE: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
    TO: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i8042.nomux i8042.noloop"
    5) Save
    6) Open Terminal
    7) sudo update-grub
    8) sudo shutdown now
    (Normal reboot will not work.)

    Sound Fix
    1) Open Terminal
    2) sudo gedit /usr/share/pulseaudio/alsa-mixer/paths/analog-output-speaker.conf
    3) In the analog-output-speaker.conf file,
    CHANGE:
    [Element Headphone]
    switch = off
    volume = off
    TO:
    [Element Headphone]
    switch = off
    volume = merge
    override-map.1 = all
    override-map.2 = all-left,all-right
    CHANGE:
    [Element Speaker]
    required-any = any
    switch = mute
    volume = merge
    override-map.1 = all
    override-map.2 = all-left,all-right
    TO:
    [Element Speaker]
    required-any = any
    switch = mute
    volume = off
    4) Save
    5) Open Terminal
    7) sudo reboot
