SDL_HINT_AUDIO_ALSA_DEFAULT_RECORDING_DEVICE(3)

💖 SDL_HINT_AUDIO_ALSA_DEFAULT_RECORDING_DEVICE 💖

okay bestie, so this is a page from the SDL3 FUNCTIONS manual, and it's all about telling SDL which ALSA recording device you want to be your default. let's get into it 🎀

---

✨ NAME ✨

SDL_HINT_AUDIO_ALSA_DEFAULT_RECORDING_DEVICE — literally just here to Specify the default ALSA audio recording device name. no cap, that's the whole job 💅

---

🌸 SYNOPSIS 🌸

#include <SDL3/SDL_hints.h>

#define SDL_HINT_AUDIO_ALSA_DEFAULT_RECORDING_DEVICE "SDL_AUDIO_ALSA_DEFAULT_RECORDING_DEVICE"

like, that's the header you gotta pull in, and that's the exact string macro name. copy it character for character, bestie, do not freestyle it 🙈

---

🦋 DESCRIPTION 🦋

so this variable is a specific audio device to open for recording, and it kicks in when the "default" audio device is used. it's giving "i don't want whatever ALSA feels like today, i want THIS one" energy 👑

but here's the tea 🍓 — if this hint isn't set, SDL will check SDL_HINT_AUDIO_ALSA_DEFAULT_DEVICE before choosing a reasonable default. so it's not just gonna vibe-check into the void, it has a backup plan.

⚠️ and this part matters fr fr: this hint should be set before an audio device is opened. set it early, or it's not gonna help you. timing is everything, periodt.

---

🌈 AVAILABILITY 🌈

this hint is available since SDL 3.2.0. so if you're on something older, no shade but you're out of luck 😭

and that's the whole page, bestie!! this one's from the Simple Directmedia Layer girlies, SDL 3.4.18 era. mwah, go set that hint before opening your device 🫶✨
