snd_ac97_tune_hardware(9)

snd_ac97_tune_hardware 💅 (straight from the Kernel API Manual, bestie)

✨ NAME ✨

snd_ac97_tune_hardware — tune up the hardware, no cap 🎀

✨ SYNOPSIS ✨

int snd_ac97_tune_hardware (struct snd_ac97 *ac97 , const struct
       ac97_quirk *quirk , const char *override );

✨ ARGUMENTS ✨

• ac97 — the ac97 instance, aka the main character we're about to glow up 💅
• quirk — quirk list, the vibes checklist
• override — explicit quirk value (overrides the list if non-NULL). So if you pass something here, it's giving "I said what I said" and the list gets ignored, periodt.

✨ DESCRIPTION ✨

So basically this function does some workaround for each pci device, such as renaming of the headphone (true line-out) control as "Master". 🎧➡️👑

The quirk-list must be terminated with a zero-filled entry. Like, don't forget the sentinel, bestie — it's the "bye bye" at the end of the list or the whole thing is lowkey undefined vibes. 🫶

✨ RETURN ✨

Zero if successful, or a negative error code on failure. Slay when it's zero, cry when it's negative 😭
