snd_hda_mixe...p_switch_get(9)

hey bestie 💖 welcome to the snd_hda_mixe...p_switch_get(9) page from the Kernel API Manual — yes, that whole mouthful is the title, and we're gonna get through it together ✨

💖 NAME 💖

• snd_hda_mixer_amp_switch_get — Get callback for a standard AMP mixer switch

✨ SYNOPSIS ✨

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

🎀 ARGUMENTS 🎀

• kcontrol — ctl element. That's the control element, bestie 💅
• ucontrol — pointer to get/store the data

🦋 DESCRIPTION 🦋

Okay so here's the vibe: the control element is supposed to have the private_value field set up via HDA_COMPOSE_AMP_VAL*() or related macros. That's the setup it's counting on, no cap 🫶
