If anyone wants to try out the new Ubuntu 16.04 LTS on their Intel Compute Stick but would also like sound and wifi then I've created a patched kernel.
First download and install Ubuntu 16.04 and then
sudo chmod 700 linuxium-patch-xenial-ics.sh
This will install my patched kernel together with the required wifi firmware. As it is a patched kernel it means it will not get any automatic updates from Canonical so it should only be used for testing purposes. Currently only Intel Compute Sticks are supported.
It is also still in development and as everything is extremely new not everything has been exhaustively tested so your feedback is appreciated.
Credit goes to Pierre-Louis Bossart for the original HDMI audio patches which I've backported to the current 'xenial' kernel and to Bastien Nocera (hadess) for the wifi source.
