The Audio Compatibility Patch (ACP) is a popular Magisk module designed to fix issues where music and streaming apps like Spotify or Pandora fail to process audio effects from equalizers (such as ViPER4Android or JamesDSP). Key Features & Purpose

The Full version surpasses the Basic version because it solves two problems at once: compatibility and available processing. You do not need to hunt down a separate AudioFX APK. It is all in one package.

Troubleshooting Common Issues

Even with the "Full" version, things can go wrong. Here is your troubleshooting checklist.

Because the "Full" version disables certain power-saving deep sleep states in the audio DSP (to prevent stuttering), you may see a negligible drain of 1-2% per day. For 99% of users, this is unnoticeable. However, if you are on a legacy device (Android 9 or older), the "Full" version can cause the audio HAL to keep a wakelock.

You connect to your car's Bluetooth. Your music is clear, but when you take a call, the other person hears silence or static. ACP fixes the sco_routing for Bluetooth Headset Profile (HSP).
