snd_hdac_apl...stream_setup(9)

✨ NAME ✨

snd_hdac_apl_host_stream_setup — bestie, this is the one that sets up a HOST stream following the exact procedure that's recommended for ApolloLake devices 💅 (this page lives in the Kernel API Manual, iykyk)

🎀 SYNOPSIS 🎀

int snd_hdac_apl_host_stream_setup(struct hdac_stream *hstream, bool code_loading);

🦋 ARGUMENTS 🦋

• hstream — the HDAudio stream you want to set up. Like, the actual stream object, hand it over 🫶
• code_loading — a bool that tells us whether this stream is for PCM or for code-loading. That's literally the whole question it's asking, no cap.

🌸 RETURN 🌸

Returns zero on success, or a negative error code if things went sideways 😭 (standard Unix deal, you already knew that).
