💅 sof_ipc4_get_audio_fmt(9) 💅

okay so this is a page from the Kernel API Manual, bestie, and it's genuinely so niche and so iconic at the same time. it's all about sof_ipc4_get_audio_fmt — a function that pulls the list of available audio formats out of swidget->tuples. yep. that's the whole vibe. let's get into it 🎀

---

✨ NAME ✨

sof_ipc4_get_audio_fmt — get available audio formats from swidget->tuples

like literally, that's its job. it goes and fetches the audio formats that are chillin' inside swidget->tuples. no cap 🫶

---

🌸 SYNOPSIS 🌸

int sof_ipc4_get_audio_fmt (struct snd_soc_component *scomp , struct
snd_sof_widget *swidget , struct sof_ipc4_available_audio_format
*available_fmt , struct sof_ipc4_base_module_cfg *module_base_cfg );

it returns an int, and yes it takes four args, we love a four-arg moment 💅

---

🦋 ARGUMENTS 🦋

• scomp — pointer to pointer to SOC component. yes, pointer to pointer. double the pointer, double the slay ✨
• swidget — pointer to struct snd_sof_widget containing tuples. this is where the audio formats are actually living, iykyk 👑
• available_fmt — pointer to struct sof_ipc4_available_audio_format being filling in. that's what the page says, "being filling in", and honestly? we're keeping it exactly as is. it's the format struct that's getting filled in 🧚
• module_base_cfg — Pointer to the base_config in the module init IPC payload. capital P, we respect it 🔥

---

⭐ RETURN ⭐

0 if successful. that's it. that's the return value. zero means we ate and left no crumbs 🍓

---

🌈 SEE ALSO 🌈

• Kernel file ./sound/soc/sof/ipc4-topology.c — go read it, bestie, that's where the lore lives 💜

---

lowkey important reminder: keep every path and param name exactly as written, no renaming, no merging, no inventing. we're cute but we're accurate 💀

---

okay that's the whole page!! short and sweet and honestly kind of a main character for a kernel function. this gem comes to you from ./sound/soc/sof, dated October 2026 — so yes, it's lowkey from the future, and it's giving time traveler energy 🦋✨ bye bestie, go fill in those formats 💖
