💖 snd_hda_cod..._init_stereo(9) — Kernel API Manual 💖

okay so bestie, welcome to the Kernel API Manual entry for snd_hda_codec_amp_init_stereo ✨ (yes the title is truncated with ... in the header, that's just how the page rolls, no cap — the real name is in NAME, keep scrolling)

🌸 NAME 🌸

snd_hda_codec_amp_init_stereo — literally initializes the stereo AMP value 🎀

🦋 SYNOPSIS 🦋

int snd_hda_codec_amp_init_stereo (struct hda_codec *codec , hda_nid_t
nid , int dir , int idx , int mask , int val );

it's giving "one function, six arguments, zero chill" 💅

✨ ARGUMENTS ✨

  • codec — the HDA codec, the main character of this whole operation 👑
  • nid — the NID to read the AMP value from, iykyk 🎯
  • dir — either #HDA_INPUT or #HDA_OUTPUT, pick your fighter 🌈
  • idx — the index value, and heads up: it only matters for the input direction 🙈
  • mask — the bit mask to set, aka which bits we're touching 🎀
  • val — the bits value to set, aka what we're putting there ⭐

💜 DESCRIPTION 💜

fr fr, all this does is call snd_hda_codec_amp_init for both stereo channels 💖 two channels, one init, iconic behaviour.

🔥 SEE ALSO 🔥
