snd_hda_codec_register(9)

💅 snd_hda_codec_register(9) — the "Finalize codec initialization" one

okay so bestie, you found a page from the Kernel API Manual (yes, that's the manual name, it's giving very serious kernel energy ✨) and it's called snd_hda_codec_register. It's a tidy little function and honestly the whole thing fits in a couple of lines. Let's vibe check it together 🫶

🌸 NAME 🌸

snd_hda_codec_register — literally Finalize codec initialization 💖 that's the whole job, that's the assignment, she ate and left no crumbs

---

✨ SYNOPSIS ✨

void snd_hda_codec_register (struct hda_codec *codec );

no cap, that's the entire signature — void in, void out, no return value to stress about 😌

---

🎀 ARGUMENTS 🎀

• codec — the codec device you wanna register. that's it. that's the whole list 🦋

---

💫 DESCRIPTION 💫

so the actual description here is tiny, but it's important bestie: this one is also called from hda_bind.c 👀 like, not just from wherever you're calling it — that file has a whole extra caller situation going on. iykyk.

fr fr don't skip the little sentences, that's where the lore lives 🙈

🔥 SEE ALSO 🔥
