G'day,
I've a laptop on my lab bench with a Realtek ALC5645 codec attached to an Intel(R) Atom(TM) x5-Z8350. Built-in speakers work properly. Not working are;
- headphones; only ever silent playback,
- built-in microphone; only ever silent recording,
- headset microphone; only ever silent recording,
- there is no response to headset jack insertion or removal,
It has never worked.

I'm testing with 4.11.1 kernel on Ubuntu 17.04.
I've tried latest UCM/chtrt5645/HiFi.conf c8b344c.
I've tried using alsamixer to experiment with some of the 253 or so controls.
I don't have a datasheet. (My previous work was with ALC5631, for which I do have a datasheet, and it was very helpful!)
Also in the box was an NTC thermistor cabled to a TRRS plug, which may suggest a design with switchable decoupling capacitors.
