--- Comment #16 from Ivan <bsd at abinet.ru> ---
I have Dell XPS13 (Skylake) with ALC256

After I applied this patch, sound is greatly improved (before it was distorted 
beyond recognition).

However, some static noises left, actually they reflect my actions, changing
tone and loudness when I switch windows, scrolling and so on. Noise look the
same for 100 vol or 1 (vol = 0 or pcm=0 shut it completely). Onboard speakers
are OK.

I looked into linux quirks and found several fixes for this troublesome codec.
I can't figure out which you applied, was it
ALC256_FIXUP_DELL_XPS_13_HEADPHONE_NOISE ?

Maybe, something can be improved ?
