Public bug reported:
No sound at all, neither in headphones nor in speakers.
Have tried without success:
jack-retask
latest alsa drivers with DKMS
various options set in /etc/modprobe.d/alsa-base.conf
Codec seems to be supported:
grep "Codec:" /proc/asound/card*/codec*
/proc/asound/card0/codec#0:Codec: Conexant CX20753/4
/proc/asound/card0/codec#2:Codec: Intel Skylake HDMI
