snd_hda_attach_beep_device(9)

📦 version 7.3.1, in nixpkgs unstable

omg bestie, welcome to the snd_hda_attach_beep_device(9) page in the Kernel API Manual 💖✨ This one is all about attaching a beep input device, and yes she is serving kernel-internals realness.

🌸 NAME 🌸

<pink>snd_hda_attach_beep_device</pink> — attach a beep input device 🎀

🦋 SYNOPSIS 🦋

int snd_hda_attach_beep_device (struct hda_codec *codec , int nid );

🍓 ARGUMENTS 🍓

  • codec — the HDA codec, aka the main character here 👑
  • nid — the beep NID, periodt ✨

💅 DESCRIPTION 💅

So the vibe is: attach a beep object to the given widget. 🫶

But listen — if the beep hint is turned off explicitly, or if the beep_mode of the codec is turned off, this does nothing. Like, literally nothing, bestie. (The original wording is “this doesn't nothing,” and I am obsessed with the grammar but not confused about the behavior 😭💀)

Currently, only one beep device is allowed to each codec. One beep device per codec, that is the rule 💖
