STRUCT SND_SOC_ACPI_ENDPOINT(9)

💖 struct snd_soc_acpi_endpoint(9) — Kernel API Manual 💖

okay bestie, listen up — this is a page from the Kernel API Manual, and it's all about struct snd_soc_acpi_endpoint, aka the little descriptor that tells you about an endpoint. it's tiny, it's four u8s, and it's lowkey doing a lot. let's get into it 🫶

✨ NAME ✨

struct snd_soc_acpi_endpoint — endpoint descriptor. that's it, that's the whole vibe. 💅

---

🌸 SYNOPSIS 🌸

here's the whole struct, bestie, look at her:

struct snd_soc_acpi_endpoint {
    u8 num;
    u8 aggregated;
    u8 group_position;
    u8 group_id;
 };

four little fields. no cap. 🎀

---

🦋 Members 🦋

okay so let's go field by field, because each one has lore:

• num — the endpoint number. this one is mandatory, and it has to be unique per device. not optional, not negotiable, mandatory. periodt. 👑
• aggregated — it's either 0 (independent) or 1 (logically grouped). that's the whole range, don't get creative. 💀
• group_position — the zero-based order. and listen: this only matters when aggregated is 1. if it's not aggregated, this field is just sitting there, minding its business. 🙈
• group_id — the platform-unique group identifier. same deal: only when aggregrated is 1 (yes, that's spelled exactly how the original spells it, don't come for me 🫶). it's giving "you only get a group if you're actually grouped." 🧚

heads up bestie: if aggregated is 0, then group_position and group_id aren't relevant — they're group-only fields, iykyk.

that's the page!! mwah 💜

sign-off time: this iconic little number lives over in ./include/sound, and it's dated October 2026 — and the page itself is struct snd_s...cpi_endpoint(9), yes the abbreviations are real, yes they're adorable, no we're not fixing them. bye bestie, go read your headers 🎀✨🦋
