snd_soc_runtime_set_dai_fmt(9)

💅 snd_soc_runtime_set_dai_fmt(9) 💅

okay so bestie, welcome to the Kernel API Manual page for snd_soc_runtime_set_dai_fmt(9) — yes the title is a mouthful, no we are not renaming it, it's iconic as-is 🎀

---

✨ NAME ✨

snd_soc_runtime_set_dai_fmt — change the DAI link format for an ASoC runtime 🦋

---

🌸 SYNOPSIS 🌸

int snd_soc_runtime_set_dai_fmt (struct snd_soc_pcm_runtime *rtd ,
unsigned int dai_fmt );

---

💖 ARGUMENTS 💖

• rtd — the runtime where we're switching up the DAI link format, like it's getting a whole new look 💅
• dai_fmt — the brand-new DAI link format, the main character of this whole operation ✨

---

🫶 DESCRIPTION 🫶

okay so here's the vibe: this function updates the DAI link format for all the DAIs connected to the DAI link of that specified runtime. not just one, not just the cute ones — all of them, fr fr 🔥

---

😭 NOTE 😭

heads up bestie 🚨 if your setup has a static format, you gotta set the dai_fmt field in the corresponding snd_dai_link struct instead of calling this function. no cap, that's the move.

Returns 0 on success — otherwise a negative error code (iykyk, sad girl hours 💀).
