Hackintosh didn't set speaker as default audio output

[vk3a]

Hi everyone. Recently my working hackintosh (Sierra 10.12.4) hasn't remembered last selected audio output (speaker in particular). Every time I reboot the machine, it always sets headphone as default output. I also have El Capitan installed on another HDD with the same kexts and it works well so far. Thinking it was something to do with AppleALC and Lilu kexts, but updating these stuffs didn't help. Any suggestions? Thanks for reading.

Works as designed. Unplug Headphones before shutting down.

Thanks for replying, toleda. I think it's not the point because no matter I plug headphone or not, it'll be set as default output, plus El Capitan is working fine at the time of writing.

Post #1 describes a different problem.
Post #3, front panel connector failure, unplug front panel cable from motherboard.

Nope, unpluging front panel connector didn't fix the problem either.

Motherboard/front panel cable, impossible.
