Public bug reported:
I wanted to try Linux again on this machine and the tons of
troubleshooting since release got a bit better, but the sound is still a
bit strange.
So after changing distributions I installed Xubuntu 16.04 Beta 1 today with
kernel 4.4.0-8 and sound isn't working because the 3,5 mm device is completely
missing. PulseAudio is only showing the HDMI output.
I got the sound working by downloading kernel 4.3.6 from the Ubuntu kernel
archives, although then it looks like it is running in HDA mode instead of I2S
(which I don't like because Dual Boot).
Let me know if there is anything else I can do to track down the
problem.
