snd_hda_mul..._dig_prepare(9)

💅 snd_hda_multi_out_dig_prepare — straight outta the Kernel API Manual

okay so bestie, gather round, because we're about to get into the digital-out stream situation and honestly? it's giving "small function, big responsibilities." ✨

🌸 NAME 🌸

snd_hda_multi_out_dig_prepare — literally just prepare the digital out stream. that's the whole vibe. that's the assignment. 🎀

🦋 SYNOPSIS 🦋

int snd_hda_multi_out_dig_prepare (struct hda_codec *codec , struct
       hda_multi_out *mout , unsigned int stream_tag , unsigned int format ,
       struct snd_pcm_substream *substream );

five arguments, one int coming back at you. no cap. 🔥

🍓 ARGUMENTS 🍓

• codec — the HDA codec. like, the actual codec. the main character of this whole operation 👑
• mout — the hda_multi_out object. yes that's its whole government name 🫶
• stream_tag — the stream tag you're assigning. hand it over, bestie 🎯
• format — the format id you're assigning. also just... here. take it 💌
• substream — the PCM substream you're assigning. last one, promise 🌈

okay that's genuinely everyone, i counted, we're not leaving a single one out, the way i would never leave you on read 💖

ngl there's no extra description beyond this, so no extra lore to spill — what you see is what you get, fr fr. the synopsis, the args, and the squad. periodt. 💅
