✨ snd_hda_create_dig_out_ctls(9) ✨

okay so bestie, we're deep in the Kernel API Manual today and this one is a little function with a big job 💅 it's snd_hda_create_dig_out_ctls, and yes the name is a mouthful, but it's literally just here to spin up your Output SPDIF-related controls. digital audio out, but make it official 🎀

🌸 NAME 🌸

snd_hda_create_dig_out_ctls — create Output SPDIF-related controls 🎧✨

---

🦋 SYNOPSIS 🦋

int snd_hda_create_dig_out_ctls (struct hda_codec *codec , hda_nid_t
       associated_nid , hda_nid_t cvt_nid , int type );

---

💖 ARGUMENTS 💖

• codec — the HDA codec, aka the main character of this whole situation 👑
• associated_nid — the NID that the new ctls get associated with 🫶
• cvt_nid — converter NID, keeping it cute and converting ⭐
• type — an HDA_PCM_TYPE_* value. creates controls related with the digital output ✨ called from each codec driver supporting the digital out. iykyk 🔥

🌈 DESCRIPTION 🌈

returns 0 if successful, or a negative error code 😭 that's it, that's the vibe check — no cap 💀
