As Android has evolved, some audio compatibility issues have been addressed by Google. However, the fundamental architecture that allows streaming apps to bypass effect processing remains largely unchanged. ACP continues to be actively maintained, with the variant receiving updates specifically for newer Android versions and rooting frameworks.
Magisk itself trips Knox. ACP does not cause additional damage, but once Knox is tripped, Samsung Pay and Secure Folder will not work.

Originally developed by , ahrion , and John Fawkes , ACP has undergone several iterations and continues to be actively maintained. As of version 2.5, the module has amassed over 1.8 million downloads , making it one of the most popular root modules in existence. While originally built for Magisk, modern versions of ACP are fully compatible with KernelSU and APatch as well, extending its utility to a wide range of rooted Android devices.
Many Android devices are software-locked to output audio at 48kHz, even if your external DAC supports 192kHz or higher.
In simple terms, Android has multiple ways of handling audio: OpenSL ES, AAudio, and the legacy tinyalsa . When you install a custom ROM (like LineageOS, crDroid, or Pixel Experience) on a device not officially supported by that ROM, the audio "bridge" between the software and your specific phone hardware often breaks.

No measurable drain. It only applies systemless overlays at boot and does not run background processes.
