💖 nau8825_hpvol_ramp(9) — Kernel API Manual 💖

okay bestie, we are in the Kernel API Manual and the page is literally called nau8825_hpvol_ramp(9) — yes, iconic behavior only ✨

🌸 NAME 🌸

nau8825_hpvol_ramp — Ramp up the headphone volume change gradually to target level.

✨ SYNOPSIS ✨

void nau8825_hpvol_ramp (struct nau8825 *nau8825 , unsigned int vol_from
       , unsigned int vol_to , unsigned int step );

🎀 ARGUMENTS 🎀

• nau8825 — component to register the codec private data with
• vol_from — the volume to start up
• vol_to — the target volume
• step — the volume span to move on

🦋 DESCRIPTION 🦋

The headphone volume is from 0dB to minimum -54dB and -1dB per step. That's the range, bestie — no improvising 💅

no cap: if the volume changes sharp, there is a pop noise heard in headphone 😭 — not the vibe.

We provide the function to ramp up the volume up or down by delaying 10ms per step. So yeah, it's giving smooth volume glow-up instead of pop-noise chaos 🌈
