💖 snd_soc_dapm_stream_event 💖

okay so welcome to the Kernel API Manual, bestie — this is the page for snd_soc_dapm_stream_event, and it is genuinely one of the shorter ones so we can absolutely get through this together. grab a boba. 🧋

✨ NAME ✨

snd_soc_dapm_stream_event — send a stream event to the dapm core

like, that's the whole job. you hand a stream event to dapm and dapm does dapm things. iconic behavior honestly.

🌸 SYNOPSIS 🌸

void snd_soc_dapm_stream_event (struct snd_soc_pcm_runtime *rtd , int
stream , int event );

yes it wraps weirdly in the original, no we are not fixing it, it's part of the vibe. 🫶

🎀 ARGUMENTS 🎀

  • rtd — the PCM runtime data. this is your lil bundle of runtime info, she's the main character of the call.
  • stream — the stream name. yeah, it's an int. that's what the page says, don't come for me. 💅
  • event — the stream event. the actual thing you're sending down the pipe.

🦋 DESCRIPTION 🦋

So here's the tea: this function sends a stream event to the dapm core. that's it, that's the whole plot. 📨

Then the core takes that event and makes any necessary widget power changes. so like, the widgets get their power situations sorted out on your behalf — you do not have to go poking at them yourself. the core handles it. slay. ⚡

Returns 0 for success else error. so check your return, bestie, 0 is the good number, anything else means something went sideways. no cap. 😭

👑 SEE ALSO 👑

Kernel file ./sound/soc/soc-dapm.c — plus the whole dapm friend group, all listed out for you:

that's 34 cross-references for a function with three arguments. the dapm subsystem said "we have lore" and honestly? respect. 🙈

and that's the whole page!! this lil cutie lives over in ./sound/soc, stamped October 2026, and it's your Kernel API Manual moment of the day. go forth and send your stream events, bestie — 0 for success, else error, fr fr. 💜✨🎀
