snd_soc_find_dai_link(9)

💅 snd_soc_find_dai_link(9) — like, the Kernel API Manual bestie ✨

okay so this one lives in the Kernel API Manual and it's literally called snd_soc_find_dai_link — and yes bestie, it does exactly what it says on the tin: it finds a DAI link 🎀

---

✨ NAME ✨

snd_soc_find_dai_link — find a DAI link 🔍💖

---

🦋 SYNOPSIS 🦋

struct snd_soc_dai_link * snd_soc_find_dai_link (struct snd_soc_card
*card , int id , const char *name , const char *stream_name );

---

🌸 ARGUMENTS 🌸

• card — the soc card, aka the main character of this whole quest 👑
• id — the DAI link ID you're trying to match, like the vibe check number 💅
• name — the DAI link name to match, and it's optional (no pressure bestie, you don't have to give it one) 🙈
• stream_name — the DAI link stream name to match, also optional 🍓

---

💜 DESCRIPTION 💜

so what this function actually does: it goes and searches all the existing DAI links of the soc card to find, like, the link with the same ID. that's the whole mission 🧚✨

but here's the tea ☕ — since DAI links may not have their unique ID, name and stream_name should also match if they're being specified. so it's giving "ID first, but we double-check with names when you hand them over" energy 😭🫶

---

⭐ RETURN ⭐

it returns a pointer to the DAI link — slay, found it 💚 — or NULL if it's not found 💀

---

🌈 SEE ALSO 🌈

• the kernel file ./sound/soc/soc-topology.c
• set_link_hw_format(9)
• soc_tplg_dai_config(9)

go read those too, iykyk 📚🔥

---

ngl bestie, if that NULL comes back, your link genuinely isn't there — that's not me being dramatic, that's just the return value 😌

mwah 💋 that's the whole page — brought to you from ./sound/soc, dated October 2026, and the title card still reads snd_soc_find_dai_link(9). catch you in the next manpage, bestie 🫶💖
