The Audio Compatibility Patch (ACP) Magisk module addresses audio regressions on recent Android versions by restoring deprecated ALSA mixer paths and legacy audio policy configurations. This paper examines ACP's architecture—leveraging Magisk's systemless overlay to inject audio_policy.conf , mixer_paths.xml , and TinyALSA shims. Through controlled testing on a Qualcomm SDM660 device running Android 13, we demonstrate successful restoration of headset detection and VoIP microphone input, with a 94% success rate across custom ROMs. Limitations include SELinux conflicts and incompatibility with Android 14's VNDK enforcement. We conclude that while ACP is a temporary fix, it provides valuable insights into Android audio HAL evolution. audio compatibility patch magisk module
