💖 snd_hdac_stream_sync(9) — Kernel API Manual 💖

okay so bestie, this is a page from the Kernel API Manual and it's about syncing your HD-audio streams with a start/stop trigger operation. it's short, it's sweet, and it's lowkey the glue that keeps your FIFOs from acting a mess ✨

🌸 SYNOPSIS 🌸

void snd_hdac_stream_sync (struct hdac_stream *azx_dev , bool start ,
       unsigned int streams );

like, that's the whole signature. no return value, it's giving "i just do the work and leave" 💅

🎀 ARGUMENTS 🎀

  • azx_dev — the HD-audio core stream, and it's the master stream fr fr. this is the one calling the shots 👑
  • start — a bool, where true = start and false = stop. that's it, that's the whole vibe check 🦋
  • streams — bit flags of the streams you wanna sync. yes, bits. flags. plural. get into it 🌈

✨ DESCRIPTION ✨

so here's the tea, and it's genuinely simple:

  • if start = true, it waits until all FIFOs get ready. all of them. no cutting the line 🙈
  • if start = false, it waits until all RUN bits are cleared. every last one, periodt 💀

that's the entire description. iconic of it honestly. no cap, this function understood the assignment of "be concise" 🫶

🔥 SEE ALSO 🔥

okay this list is LONG and i'm obsessed with it, look at all these siblings:

like genuinely go read all of those, they're the whole friend group 💜

ngl there are no warnings, no exit statuses, no environment variables and no known bugs on this page. sometimes a manpage is just chill like that 🧚

sign-off time 🎀 this little beauty lives in ./sound/hda/core, the date on it is October 2026, and the whole thing is filed under snd_hdac_stream_sync(9). mwah, go sync some streams bestie 💖✨🍓
