Hmm. I suspect I have been bitten by this on my laptop. I no longer have sound.

I also suspect that it's purely because "make oldconfig" doesn't work,
and probably turned off my old Intel HDA settings. Or something.

Renaming config parameters is *bad*. I've harped on the Kconfig phase
of the kernel build probably being our nastiest point, and a real pain
point to people getting involved with development simply because
building your own kernel can be so daunting with hundreds of fairly
esoteric questions.

And it looks like this pull has basically made it all worse, by making
previous answers to those esoteric questions null and void.

Now, it could be something else - like a real actual bug in the code -
but it does smell a bit like just silly Kconfig noise.

My laptop seems to think I have headphones attached, and there is no
sound. I think it's some generic HDA setup (the kernel messages do say
"autoconfig for Generic").

This is my bog-standard Intel laptop from many years ago (Dell xps13).
I am seeing snd_hda_intel and hda_codec_hdmi, but it *used* to pick
out ALC3271 and apparently that just magically went away

I think that's realtek, but when I enable it, I get this mess of
"which realtek", which I have no idea because the ALC3271 that the
kernel used to print out is not mentioned.

This was _singularly_ unhelpful. If the answer is "just enable
everything because you can't know which codec you have", then why have
the question in the first place?

This whole "ask people questions that they cannot know the answer to"
is a disease. And then the questions then randomly change, that's
*worse*.
