💅 snd_hda_crea...pdif_in_ctls — Kernel API Manual ✨

okay so bestie, welcome to the glow-up of snd_hda_crea...pdif_in_ctls(9) — yes that's the truncated-looking name, no it's not a typo, it's just the man page being ✨iconic✨ and abbreviating. This is the Kernel API Manual energy, and we're getting into SPDIF input controls. Let's go 🎀

---

🌸 NAME 🌸

snd_hda_create_spdif_in_ctls — literally creates the Input SPDIF-related controls 💖

---

⭐ SYNOPSIS ⭐

int snd_hda_create_spdif_in_ctls (struct hda_codec *codec , hda_nid_t
nid );

---

🦋 ARGUMENTS 🦋

• codec — the HDA codec 👑 like, the whole codec bestie
• nid — audio in widget NID 🎯 the widget id of the audio input

---

💜 DESCRIPTION 💜

So what it does: it creates the controls that are related with the SPDIF input. That's it, that's the vibe. 🫶

It gets called from each codec driver that supports the SPDIF in — so every codec driver out here repping SPDIF in gets to call this. iykyk 💅

Returns 0 if successful, or a negative error code. So like, zero is the slay outcome, negative means something went sideways 😭
