2-Icons are very small, there was a partial solution by enlarging the fonts but it, still some icons are small.

A:

Someone over on HP's support forums found a solution for the lack of sound. You should make sure you back up your computer first, as it does involve modifying GRUB's configuration. The steps are:

Edit grub config by doing:
'sudo vim /etc/default/grub'
Edit the line:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash'"
To:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=vendor acpi_osi='!Windows 2013' acpi_osi='!Windows 2012'"
Then run:
'sudo update-grub'
Reboot TWO times.

You may need to alter volume or mute settings afterwards.
