no analog sound, only HDMI

Asked by voirev

Xubuntu 14.10 (64), Slimbook NC11- Intel N2807 (Bay Trail?) , Uefi 32! Aptio
Everything seems to work ok, but a sound...
no analog option, only HDMI in Pavucontrol or alsamixer

card detected, codec detected (Intel Valleyview2 HDMI)
speakers tests show HDMI should work, but I need laptop's internal speakers.

Help, please!

Probably it's just a lack of hardware sound card support which I thought I would be provided with 3.16 kernel ( I tried also 3.18, 3.19...)
Similarly a backlight didn't work in Ubuntu 14.04 but works like a charm in 14.10 just out of box. So I / we must wait ...
