STRUCT SOF_IPC4_ASRC(9)

🦋 struct sof_ipc4_asrc(9) — ASRC config data 🦋

okay so bestie, welcome to the Kernel API Manual ✨ — this is the page for struct sof_ipc4_asrc, and it's literally the ASRC config data struct, no cap. It's giving "small struct, big responsibilities" energy 💅

---

🌸 SYNOPSIS 🌸

Like, here's the whole thing, character for character, don't @ me:

struct sof_ipc4_asrc {
    struct sof_ipc4_asrc_data data;
    struct sof_ipc4_available_audio_format available_fmt;
    struct sof_ipc4_msg msg;
 };

Three members. That's it. Iconic behavior honestly 🎀

---

💖 Members 💖

• data — the IPC base config data, aka the main character of this struct 👑 it's the foundation everything else sits on.
• available_fmt — the available audio format 🎧 yes bestie, the formats that are, like, available.
• msg — the IPC4 message struct containing header and data info 📨 it's carrying the header and the data info, it's a whole dual-threat situation.

---

ngl bestie, this is a kernel API page — read the struct, respect the struct, and don't go inventing fields that aren't there 🙈
