No soundcard on Thinkpad X250

You still have some of the SND_* stuff built as "Y" built in instead of modules. Built in doesn't show in lsmod.

Starting with the snd section of drivers, every spot that you have selected "*" try "M" if it succeeds then it will be a module,
there are a few selections that will only allow Y/N but those won't build as module, they're options for modules/built-in.

The problem with mixing is that some of the built-in selections won't be activated when a module is loaded after it.
That's why I said it all needs to be cohesive.

4.14.83 is a pretty new kernel, at least patch wise, and should support all your hardware.

Edit to add: 4.19.9 is new as of yesterday. If you haven't emerge --sync'd yet, then 4.19.8 should work.

liquidvel,

your portage is not up to date. Anyhow, using the latest kernel was just an idea, it may not help at all.

Evidently 4.19.9 had some verification problems https://forums.gentoo.org/viewtopic-p-8290604.html#8290604

should work with a newer sync.

Starting with Device-Drivers->Sound Card Support
Then Advanced Linux Sound Architecture
And all sub areas under this should all be selected as module "M"
Everything under HD-Audio especially HD Audio PCI which select snd_hda_intel
Everything under Generic sound devices, etc

You just have to go through each area one by one and try to make them all modules.
If you have it selected then hit the M key if it allows it to be a module it will change other wise it won't.

After that, rebuild the kernel, and all modules then install modules and kernel and restart.

You're getting codec not bound because there are some things that are still built-in and they're trying to load but the base system which is part modular isn't loaded yet.
So you're getting screwy results.

Edit to add: This is from my laptop, it's not lenovo but does use intell stuff and is pretty similar to what you have,
It's a section of SND* stuff and how it looks from .config

Flipping to

Neddy, I wasn't sure if flipping from "y" to "m" on sound would flip everything under it automatically, or if it would just deactivate it.
