snd_hda_jack_detect_state(9)

🌸 NAME 🌸

okay so bestie, welcome to the snd_hda_jack_detect_state(9) page from the Kernel API Manual 💖 — this one is literally about querying a pin’s Presence Detect status.

✨ SYNOPSIS ✨

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

🎀 ARGUMENTS 🎀

• codec — the CODEC to sense 👀
• nid — the pin NID to sense 📍

🦋 DESCRIPTION 🦋

So the way this works is: you query the pin’s Presence Detect status, and it returns that status as one of these three iconic little values 💅

• HDA_JACK_NOT_PRESENT
• HDA_JACK_PRESENT
• HDA_JACK_PHANTOM

That’s the whole vibe check: ask the pin what’s up, get back one of those states. no cap ✨
