Bluetooth Volume Booster is a systemless KernelSU and Magisk package designed to unlock fine-tuned volume control and Hi-Res audio routing. It safely overrides Android's volume limits and audio resampling architecture without touching the core system partition.

Technical Details

This package systemlessly restructures the Android audio flow to deliver bit-perfect audio directly to hardware. It forces 48kHz native output for speakers to bypass unnecessary resampling while enabling direct_pcm routing up to 384kHz for USB DACs and 192kHz for wireless Bluetooth codecs.

Core Features of Bluetooth Volume Booster

Volume Control: Grants 150-step fine adjustment while disabling Bluetooth absolute volume and the safe media warning.
Hi-Res Routing: Enables bit-perfect direct_pcm output at 384kHz for USB DACs and 192kHz for wired connections.
Codec Support: Activates LDAC, LHDC v5, aptX Adaptive, and SBC high bitrate modes alongside A2DP Offload.
Hardware Fixes: Attempts to disable LowPerfMode auto-gain features specifically for NX729J (RedMagic 8 Pro) and SM8550 devices.

Support & Requirements

Requires Android 10 or newer and a compatible root manager like Magisk or KernelSU.

How to Install Bluetooth Volume Booster
