snd_soc_dapm_put_pin_switch(9)

💅 snd_soc_dapm_put_pin_switch(9) — like, the Kernel API Manual's own main character

okay so bestie, welcome to the Kernel API Manual, section 9. Today's episode: snd_soc_dapm_put_pin_switch. It's short, it's sweet, it's giving "one job and she does it." Let's go 🎀

✨ NAME ✨

snd_soc_dapm_put_pin_switch — the one that sets information for a pin switch. that's it. that's the whole vibe 🦋

---

🌸 SYNOPSIS 🌸

int snd_soc_dapm_put_pin_switch (struct snd_kcontrol *kcontrol , struct
       snd_ctl_elem_value *ucontrol );

like look at her. two args, returns an int, no drama, no cap 🔥

---

🎀 ARGUMENTS 🎀

• kcontrol — the mixer control, bestie. your lil handle on the thing.
• ucontrol — the Value. capital V, she's important 💅

---

👑 DESCRIPTION 👑

so here's the tea: this is a callback ✨ it's the function that provides information for a pin switch that was added at the card level. that's literally it, and honestly? iconic. she shows up, she reports the info, she leaves. no notes 🙈

ngl this is the kind of function that just exists so the card-level pin switch can do its thing — you're not here to overthink her, you're here to appreciate her 🌈

psst — snd_soc_dapm_info_pin_switch(9), snd_soc_dapm_get_pin_switch(9) and snd_soc_dapm_put_pin_switch(9) are the sibling trio, so if you found one you found the set 😭💜

and that's the page!! mwah 💋 this one's sourced from ./sound/soc, dated October 2026, and filed under snd_soc_dapm_put_pin_switch(9) — go forth and set that pin switch info, bestie, you got this 🍓🧚⭐
