By the way i know the audio-bug but it's not important, are there more issues like wireless issues, screen flickering, pen digitizer etc.? On internet there are any information on this newest spectre x360. Thanks as always to this wonderful community.
In general it is not easy to get Linux installed on Skylake and KabyLake laptops because of the difficulty of installing from a usb disk. On my Spectre 13-v which is a Sky Lake I would up running Kubuntu 16.04 as a virtual machine from Windows rather than a dual boot. That was about a year ago and I have not tried again recently.
