snd_hda_code...date_widgets(9)
π¦ NAME π¦
okay so bestie, this whole page is about snd_hda_codec_update_widgets β and honestly the subtitle says it all: it refreshes widget caps and pin defaults. that's the whole job. π
(also hi, we're in the Kernel API Manual today β the running header is lowkey truncated to snd_hda_code...date_widgets(9) but we know exactly who she is β¨)
β¨ SYNOPSIS β¨
int snd_hda_codec_update_widgets (struct hda_codec *codec );
π«Ά ARGUMENTS π«Ά
codecβ the HDA codec. that's the one you're handing over. the codec in question. the main character π
π₯ DESCRIPTION π₯
So here's the teaaaa π β this function will forcibly refresh the all widget caps and the init pin configurations of the codec you passed in.
Not a cheeky little re-check. Not a "only if it changed". Forcibly. it just goes in and redoes the whole thing, no questions, no vibes check, no apology π slay honestly.

okay that's the page!! π this one lives in the Kernel API Manual, straight outta ./sound/hda/common, and it's dated October 2026 β so she's from the future and still refreshing widgets. iconic. literally obsessed. bye bestie πππ
