Look at her. 24 constants, all lined up, absolutely iconic 👑

🧚 Constants

okay so here's the thing — every single one of these is marked -- undescribed -- in the source. That's not me being lazy, that's the actual docs being like "figure it out bestie 💀". So here they all are, in order, so you at least know they exist:

  • SDCA_CTL_ENTITY_0_COMMIT_GROUP_MASK — -- undescribed -- in the docs 🙈 the name's all you get
  • SDCA_CTL_ENTITY_0_FUNCTION_SDCA_VERSION — -- undescribed --, no writeup for this one either
  • SDCA_CTL_ENTITY_0_FUNCTION_TYPE — -- undescribed -- fr fr
  • SDCA_CTL_ENTITY_0_FUNCTION_MANUFACTURER_ID — -- undescribed -- 😭
  • SDCA_CTL_ENTITY_0_FUNCTION_ID — -- undescribed --, that's it, that's the description
  • SDCA_CTL_ENTITY_0_FUNCTION_VERSION — -- undescribed -- bestie
  • SDCA_CTL_ENTITY_0_FUNCTION_EXTENSION_ID — -- undescribed -- 🦋

🦋 DESCRIPTION 🦋

These are the Control Selectors for Entity 0, straight out of the SDCA specification v1.0, Section 6.7.1.1. That's the source of truth, bestie — go read the spec if you want the lore, because this page is just the roster 😌

like I said. long. but we read all of them 💖

also the kernel file line is Kernel file ./include/sound/sdca_function.h — just so you have the exact path, bestie 🍓

k bye ily, this page came from ./include/sound and it's dated October 2026 — go forth and select your controls 💜✨
