okay so bestie, welcome to the Kernel API Manual entry for snd_hda_multi_out_dig_open(9) and honestly? she's short, she's specific, she's iconic. no notes.

that's the whole tag list, every single one, don't skip anybody bestie 🫶 — and yeah, the neighbors include snd_hda_multi_out_dig_prepare(9), snd_hda_multi_out_dig_cleanup(9) and snd_hda_multi_out_dig_close(9), so this is very much a family situation.

lowkey the whole page is just: she opens the digital out, exclusively, with a codec and a multi_out object. that's it. that's the post. 💅

anyway the source lives under ./sound/hda/common and this little gem is dated October 2026 — mwah, stan, bye bestie 🎀✨🦋
