snd_hda_codec_setup_stream(9)

📦 version 7.3.1, in nixpkgs unstable

💅 snd_hda_codec_setup_stream — like, the kernel API manual edition ✨

okay so bestie, quick vibe check: this page lives in the Kernel API Manual, and it's all about one little function that gets your HD-audio codec ready to actually stream. no cap, it's a small one, but it's doing real work 💖

🌸 NAME 🌸

snd_hda_codec_setup_stream — set up the codec for streaming 🎧✨

🎀 SYNOPSIS 🎀

void snd_hda_codec_setup_stream (struct hda_codec *codec , hda_nid_t nid
, u32 stream_tag , int channel_id , int format );

like yes, that's the whole signature, she's lowkey serving "short and sweet" 💅

🦋 ARGUMENTS 🦋

  • codec — the CODEC to set up. this is your main character, the thing you're configuring 🫶
  • nid — the NID to set up. the specific node we're pointing at, iykyk ✨
  • stream_tag — the stream tag to pass, and fr fr it's between 0x1 and 0xf. respect the range or don't come to the party 🙈
  • channel_id — the channel id to pass, and it's zero based (so like, counting from 0, not from 1 — we love a consistent index) 💜
  • format — the stream format. literally just the format of the stream, that's the whole thing 🎀

👑 SEE ALSO 👑

okay this is the part where the friend group gets big. every one of these is invited to the group chat, and not me listing all of them 😭 but a promise is a promise, so here's the full roster:

and yeah — all of these live in the kernel file ./sound/hda/common/codec.c, so that's where you go when you wanna read the source yourself 💖

real talk: that's the entire page. no hidden options, no return value section, no bugs section — just the function, the five arguments, and the extended family. sometimes a manpage is just a manpage 🎀

✨ that's the whole thing, bestie — go set up a stream and slay ✨

this little cutie is filed under ./sound/hda/common and dated October 2026, so like… mark your calendars 💅🫶🌸
