cs4270_dai_mute(9)

💖 NAME 💖

okay bestie, meet cs4270_dai_mute(9) from the Kernel API Manual — the little function whose whole job is to enable/disable the CS4270 external mute. iconic behavior, honestly 💅

---

✨ SYNOPSIS ✨

int cs4270_dai_mute (struct snd_soc_dai *dai , int mute , int direction );

---

🎀 ARGUMENTS 🎀

• dai — the SOC DAI 🫶
• mute — 0 = disable mute, 1 = enable mute 🔇🔊
• direction — (ignored) 🙈

---

🦋 DESCRIPTION 🦋

This function toggles the mute bits in the MUTE register. periodt.

The CS4270's mute capability is intended for external muting circuitry, so if the board does not have the MUTEA or MUTEB pins connected to such circuitry, then this function will do nothing. like, literally nothing — no drama, no hidden side quest 😭

vibe check: no MUTEA/MUTEB hookup = this function is just standing there looking cute 💀
