snd_hda_mixe...p_volume_put(9)

💅 snd_hda_mixer_amp_volume_put(9) — like, the manual page bestie

okay so first things first: this is a page from the Kernel API Manual, and the function we're obsessing over today is snd_hda_mixer_amp_volume_put(9). yes the header up top is all squished like snd_hda_mixe...p_volume_put(9) — that's just the man page being dramatic, the real name is the long one. 🎀

✨ NAME ✨

snd_hda_mixer_amp_volume_put — the put callback for a standard AMP mixer volume. that's it, that's the vibe. 💖

---

🌸 SYNOPSIS 🌸

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

---

🦋 ARGUMENTS 🦋

• kcontrol — the ctl element. yeah. that one. 🫶
• ucontrol — a pointer, and its whole job is to get/store the data. iconic honestly.

---

⭐ DESCRIPTION ⭐

okay so here's the whole lore: the control element is supposed to have its private_value field set up via HDA_COMPOSE_AMP_VAL*() or related macros. that's the assignment. that's the requirement. no cap. 🔥

not me stressing that the element is "supposed to" have this set up — like, do it. set it up. the macros are right there bestie. 🙈
