snd_soc_add_card_controls(9)

📦 version 7.3.1, in nixpkgs unstable

✨ snd_soc_add_card_controls 💖

okay so bestie, welcome to the snd_soc_add_card_controls(9) page in the Kernel API Manual — yes that's the whole title, we're not copying it again, it's right there 👑 this one's short and sweet and honestly kind of iconic for it.

🌸 NAME 🌸

snd_soc_add_card_controls — add an array of controls to a SoC card. it's basically a convenience function to add a list of controls, that's the whole vibe 🎀

🦋 SYNOPSIS 🦋

int snd_soc_add_card_controls (struct snd_soc_card *soc_card , const
       struct snd_kcontrol_new *controls , int num_controls );

like, three args, returns an int, no drama ✨

💅 ARGUMENTS 💅

  • soc_card — the SoC card you're adding controls to 🫶 the main character, honestly
  • controls — the array of controls to add, all lined up ready to go
  • num_controls — number of elements in the array, so the kernel knows how far to walk down the list 🚶‍♀️

🌈 DESCRIPTION 🌈

returns 0 for success, otherwise error. that's it. that's the whole description bestie, no cap 😭 literally a one-liner and I respect it so much 💀

fr fr, if you get something that isn't 0 back, that's an error and you should handle it — that part's not a joke 🙈

🔥 SEE ALSO 🔥

kernel file ./sound/soc/soc-core.c is where the magic lives, and here's the whole squad of related functions, all of them, no skips 💜

go read them, they're all lowkey obsessed with the same subsystem 🧚

anyway bestie, this page came from ./sound/soc and it's dated October 2026 — so when you're done adding your controls, go touch some grass and remember who told you 💖✨🎀
