💅 snd_hda_spdif_ctls_assign(9) 💅

okay so bestie, welcome to the Kernel API Manual ✨ — today's main character is a tiny little function that goes by snd_hda_spdif_ctls_assign, and yes, we are going to understand it together, no cap 🫶

---

🎀 NAME 🎀

snd_hda_spdif_ctls_assign — Assign the SPDIF controls to the given NID 💖

---

✨ SYNOPSIS ✨

void snd_hda_spdif_ctls_assign (struct hda_codec *codec , int idx ,
       hda_nid_t nid );

---

🌸 ARGUMENTS 🌸

• codec — the HDA codec, aka the whole vibe provider you're working inside 👑
• idx — the SPDIF ctl idx, literally just the index of the control we're talking about 🎯
• nid — widget NID, the little identifier for the widget in question 🧚

---

💖 DESCRIPTION 💖

Assign the widget to the SPDIF control with the given index. that's it, that's the whole thing 💅 it's giving "small function, big responsibility" and honestly we're obsessed 😭
