snd_hda_codec_new(9)

✨ NAME ✨

<pink>snd_hda_codec_new</pink> — create a HDA codec. That's the whole name, bestie. This page comes from the Kernel API Manual, and the full manual-page name is snd_hda_codec_new(9). Slay.

🌸 SYNOPSIS 🌸

okay so the signature is literally this:

int snd_hda_codec_new (struct hda_bus *bus , struct snd_card *card ,
       unsigned int codec_addr , struct hda_codec **codecp );

🎀 ARGUMENTS 🎀

Four args, no skips:

• bus — the bus to assign
• card — card for this codec
• codec_addr — the codec address
• codecp — the pointer to store the generated codec

💅 DESCRIPTION 💅

Returns 0 if successful, or a negative error code. That's it — that's the return-value tea ☕.
