💅 snd_soc_dapm_sync_unlocked(9) — the Kernel API Manual page you didn't know you needed

okay so bestie, welcome to the Kernel API Manual ✨ (yes that's the manual name, we're being fancy today). This is the glow-up of the page for snd_soc_dapm_sync_unlocked(9), and no, the parenthetical (9) is not a personality trait, it's just the section number. Slay.

🌸 NAME 🌸

snd_soc_dapm_sync_unlocked — scan and power dapm paths

🎀 SYNOPSIS 🎀

int snd_soc_dapm_sync_unlocked (struct snd_soc_dapm_context *dapm );

✨ ARGUMENTS ✨

  • dapm — DAPM context 🦋

💖 DESCRIPTION 💖

okay so picture this: it walks all dapm audio paths and powers widgets according to their stream or path usage. literally every single one. it's out here doing the rounds, checking who's streaming, who's on a path, and powering accordingly. iconic behavior tbh 👑

⚠️ Requires external locking. read that again, bestie. External. It does not do the locking for you. the _unlocked in the name is not a cute nickname, it's a whole warning. you gotta bring your own lock or it's giving undefined-vibes disaster 😭

It returns 0 for success. that's it. that's the whole return situation. 💀

🔥 SEE ALSO 🔥

like, the whole crew showed up. no gatekeeping here. 🫶

🌈 sign-off era 🌈

this page lives in ./sound/soc, dated October 2026, and it's the snd_soc_dapm_sync_unlocked(9) page, obviously. go lock something externally and stay hydrated bestie 💜🧚
