STRUCT SND_SOC_JACK_ZONE(9)

💅 struct snd_soc_jack_zone(9)

okay so bestie, welcome to the Kernel API Manual — this one's a little struct from the kernel audio world and honestly? it's giving "small but mighty" 🎀

---

✨ NAME ✨

struct snd_soc_jack_zone — literally just describes the voltage zones of jack detection. that's it. that's the whole vibe 🦋

---

🌸 SYNOPSIS 🌸

here's the shape of it, copy it exactly or the compiler will absolutely come for you:

struct snd_soc_jack_zone {
    unsigned int min_mv;
    unsigned int max_mv;
    unsigned int jack_type;
    unsigned int debounce_time;
    struct list_head list;
};

---

👑 Members 👑

okay so let's meet the cast, each one's a main character in their own way:

• min_mv — start voltage, in mv. the lower edge of the zone, the beginning of the story ✨
• max_mv — end voltage, in mv. where the zone wraps up, the closing credits 💫
• jack_type — the type of jack that's expected for this voltage. like, if you're in this voltage zone, this is the jack you should be seeing 🎧
• debounce_time — the debounce time for the jack. the codec driver should wait for this duration before reading the adc for voltages. no rushing, let it settle, we love a patient queen 🧚
• list — internal list entry. lowkey just bookkeeping, but every struct needs its link in the chain, periodt 🔗

🦋 SEE ALSO 🦋

go look at the kernel file ./include/sound/soc-jack.h for the full picture, plus these two besties who hang out in the same friend group:

• struct snd_soc_jack_pin(9)
• struct snd_soc_jack_gpio(9)

ngl if you're poking at jack detection you're gonna want all three — they're a package deal 💖

and that's the page, bestie! huge shoutout to ./include/sound for being the home base, and this one's dated October 2026 — mark your calendars, this manual page is booked and busy 📅💅 slay 🫶
