Hello, I bought an HP ProBook 450 G3 last week, with AMD/ATI Radeon R7 M370 graphic system and Intel Skylake audio chip.
I set up a double-boot, with Ubuntu 16.04 and Ubuntu 14.04. The former works fine, even with the default drivers, sound included. The latter would not correctly work until : - Installation of the AMD/ATI proprietary video driver Radeon Crimson 15.12 (found at support.amd.com). The system may report bugs while building the kernel modules, but it works. When checking additional drivers, you'll be able to choose between "fglrx" and "fglrx-updates". I chose the second option and everythings works fine. - Installation of kernel 4.4.0-22-generic offered through Synaptic. The mandatory packages are linux-headers-4.4.0-22, linux- headers-4.4.0-22-generic, linux-image-4.4.0-22-generic and linux-image- extra-4.4.0-22-generic. For an easier life, I modified /boot/grub/grub.cfg to ensure the 4.4 kernel is booted by default. And voilà, the sound is here !
