[Banon, Intel Braswell HDMI, Digital Out, HDMI] No sound at all

[Samuel Siaw]

Can't hear any sound on my inbuilt speaker (but it works with lubuntu). Currently using xubuntu.

Also cannot hear any sound in my headphones when plugged in, although volume control recognizes that headphones have been plugged in.
