okay so this is the snd_hda_codec_amp_update(9) page from the Kernel API Manual, and bestie it's short but it still ate. no cap, every detail is staying. 💅

🌸 NAME 🌸

snd_hda_codec_amp_update — update the AMP mono value. periodt. ✨

🦋 SYNOPSIS 🦋

it's giving:

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

🎀 ARGUMENTS 🎀

• codec — HD-audio codec.
• nid — NID to read the AMP value.
• ch — channel to update (0 or 1).
• dir — #HDA_INPUT or #HDA_OUTPUT.
• idx — the index value (only for input direction).
• mask — bit mask to set.
• val — the bits value to set.

💖 DESCRIPTION 💖

Update the AMP values for the given channel, direction and index. that's the whole vibe check, and yes it's literally that. 🫶
