aio_src_set_param(9)

💖 aio_src_set_param(9) 💖

okay so bestie, welcome to the Kernel API Manual 💅 this page is all about aio_src_set_param, the function that sets parameters of the AIO SRC block. no cap.

✨ NAME ✨

aio_src_set_param — set parameters of AIO SRC block

🌸 SYNOPSIS 🌸

int aio_src_set_param (struct uniphier_aio_sub *sub , const struct
       snd_pcm_hw_params *params );

🎀 ARGUMENTS 🎀

• sub — the AIO substream pointer, aka the pointer to the substream you're working with 💅
• params — hardware parameters of ALSA, the settings bundle for the hardware vibe check.

🦋 DESCRIPTION 🦋

So here's the tea: this function sets a suitable setting to the input/output port that has the sampling rate converter block of AIO, so it can process whatever is specified in params. 💖 it literally goes in and hooks up the right setting for that SRC vibe.

This function has no effect if the substream is not supported rate converter. 🫠 like, none. zero. not even a little.

🔥 RETURN 🔥

• Zero if successful 🎉
• otherwise, a negative value on error 😭
