enum sdca_fu_controls — SDCA Controls for Feature Unit 🎛️✨

okay bestie, welcome to the Kernel API Manual page for enum sdca_fu_controls 💅 this is the feature-unit control selector enum and it's honestly iconic. let's get into it 🫶

NAME 🌸

enum sdca_fu_controls — SDCA Controls for Feature Unit ✨

---

SYNOPSIS 🦋

enum sdca_fu_controls {
    SDCA_CTL_FU_MUTE ,
    SDCA_CTL_FU_CHANNEL_VOLUME ,
    SDCA_CTL_FU_AGC ,
    SDCA_CTL_FU_BASS_BOOST ,
    SDCA_CTL_FU_LOUDNESS ,
    SDCA_CTL_FU_GAIN ,
    SDCA_CTL_FU_LATENCY

};

like, that's the whole squad, seven members, no cap 🎀

Constants ⭐

so here's the thing, bestie — the source doc did not describe any of these individually. every single one is just -- undescribed -- in the original. it's giving mystery, it's giving "figure it out yourself", and we're not gonna invent lore that isn't there 🙈 so here they are, exactly as listed:

• SDCA_CTL_FU_MUTE — listed as -- undescribed -- in the source 😭
• SDCA_CTL_FU_CHANNEL_VOLUME — also -- undescribed -- 💀
• SDCA_CTL_FU_AGC — yep, -- undescribed -- 🍓
• SDCA_CTL_FU_BASS_BOOST — -- undescribed -- 🌈
• SDCA_CTL_FU_LOUDNESS — -- undescribed -- 🦋
• SDCA_CTL_FU_GAIN — -- undescribed -- ✨
• SDCA_CTL_FU_LATENCY — -- undescribed -- 🎀

fr fr, none of these got a description in the original page. the names are all we've got, and we're keeping every single one of them exactly as written 👑

Description 💖
