snd_hda_jack_detect_mst(9)

📦 version 7.3.1, in nixpkgs unstable

Okay bestie, welcome to the Kernel API Manual entry for snd_hda_jack_detect_mst(9) — yes, that whole (9) is the section vibe, and we're about to make jack detection make sense, fr fr. 🎧✨

🌸 NAME 🌸

snd_hda_jack_detect_mst — detect the jack 💅

Like, the function's whole NAME-section job is literally “Detect the jack.” Short, iconic, no notes. 👑

✨ SYNOPSIS ✨

Here's the signature, copied exactly because we do not mess with code, periodt:

bool snd_hda_jack_detect_mst (struct hda_codec *codec , hda_nid_t nid ,
int dev_id );

🎀 ARGUMENTS 🎀

  • codec — the HDA codec. That's the codec in question, the main character of this audio situation 🎧
  • nid — pin NID to check jack detection. So this is the pin NID you're checking for jack detection, iykyk 📍
  • dev_id — pin device entry id. That's the pin device entry id, and yes, keep the lowercase id exactly as written 🪪
