Hi,
I tried 16.04.1 LTS image from Linuxium website (https://linuxiumcomau.blogspot.com/2016/10/running-ubuntu-on-intel-bay-trail-and.html) and I can confirm HDMI audio, ethernet and wifi works out of the box. However, Bluetooth does not work.
I downloaded ISO image and have written it to USB with mkusb application (Under Ubuntu Linux).
I tried this on PCG02U Stick PC by MeLE company (on Aliexpress it is called Fanless Ubuntu 14.04 Intel PC Stick Star Cloud PCG02U Mini PC Bay Trail Z3735F 2GB DDR3 32GB eMMC HDMI LAN WiFi).
I also tried Ubuntu 16.10 Beta 2, but it does not boot.
Regards,
M.
