okay bestie, this is a page from the Kernel API Manual, and it’s lowkey iconic for anyone messing with AIO playback ports. Let’s get into it 🫶

🌸 NAME 🌸

aio_oport_set_stream_type — set parameters of AIO playback port block

✨ SYNOPSIS ✨

int aio_oport_set_stream_type (struct uniphier_aio_sub *sub , enum
       IEC61937_PC pc );

🎀 ARGUMENTS 🎀

• sub — the AIO substream pointer. literally the substream you’re working with.
• pc — the Pc type of IEC61937. yes bestie, that exact enum value.

🦋 DESCRIPTION 🦋

So this function sets a special setting on the AIO output port block so the stream can be output via <pink>S/PDIF</pink>. That’s the whole vibe. It’s just making the output port block handle the S/PDIF stream situation 💅

It returns <green>zero</green> if successful — slay. Otherwise it returns a <red>negative value</red> on error 😭
