πŸ“œ SYNOPSIS πŸ“œ

int snd_hda_codec_set_pincfg (struct hda_codec *codec , hda_nid_t nid ,
       unsigned int cfg );

🧚 ARGUMENTS 🧚

  • codec β€” the HDA codec. that’s the codec, bestie πŸ’…
  • nid β€” NID to set the pin config. literally the NID where the pin config gets set.
  • cfg β€” the pin default config value. the pin default config value itself, no cap.

🌸 DESCRIPTION 🌸

okay so what this does: it overrides a pin default configuration value in the cache. yes, in the cache. and that value can be read by snd_hda_codec_get_pincfg at a higher priority than the real hardware value. so the cache value outranks the actual hardware value. periodt. πŸ”₯
