snd_hdac_stream_init(9)

📦 version 7.3.1, in nixpkgs unstable

💅 NAME 💅

snd_hdac_stream_init — initialize each stream (aka device)

okay so this is from the Kernel API Manual, bestie, and the whole point is literally initializing every stream (which is also called a device, iykyk) 💖

✨ SYNOPSIS ✨

void snd_hdac_stream_init (struct hdac_bus *bus , struct hdac_stream
*azx_dev , int idx , int direction , int tag );

🎀 ARGUMENTS 🎀

  • bus — the HD-audio core bus, the main character we're working with 🚌
  • azx_dev — the HD-audio core stream object you're initializing, aka the thing getting its glow-up ✨
  • idx — stream index number, its little ID number 🔢
  • direction — stream direction, and it's gonna be either SNDRV_PCM_STREAM_PLAYBACK or SNDRV_PCM_STREAM_CAPTURE 🎧
  • tag — the tag id to assign, periodt 🏷️

💫 DESCRIPTION 💫

So what it does is assign the starting bdl address to each stream (device) and initialize. that's the vibe. it sets each stream/device up with its starting bdl address, then initializes it. no cap 🫶
