PIXAML

Project Status: Unmaintained Due to a lack of free time, I have decided to stop the development of this module. Feel free to fork the repository and continue this work.

Overview

PIXAML is an audio modification module designed specifically for the Google Pixel 8 and newer devices in the Pixel family.

In these newer devices, the sound effect architecture has been migrated from HIDL to AIDL. This migration removed the audio_effects_config.xml file, so audio effects like JamesDSP, Viper4Android, etc. cannot patch it.

How It Works

To bypass this limitation, PIXAML performs the following operations:

1. Patches libaudiohal@aidl.so: It modifies /system/lib64/libaudiohal@aidl.so to utilize an additional service (vendor.aml.effect-service).
2. Restores Configuration: It adds the missing audio_effects_config.xml file back into /vendor/etc.

The binary modification is handled by patchelf, a tool specifically designed for this type of operation.

Note: The source code for the service binary used in this project can be found here: vendor_aml_effects by anonymix007.

⚠️ WARNING: Bootloop Risk & Troubleshooting

!!! THERE IS A RISK OF A BOOTLOOP !!! Always be prepared for a bootloop just in case. Have a recovery method ready before flashing.

Known Conflicts: Some Magisk/KernelSU modules can conflict with PIXAML, even if they seemingly have nothing in common (e.g., PixelXpert).

Troubleshooting Steps if Your Device Doesn't Boot:

1. Disable all modules (including non-audio ones).
2. Enable only PIXAML and reboot to check if the system boots successfully.
3. If it boots, begin enabling your other modules one by one. (For unknown reasons, establishing PIXAML as the first enabled module often resolves conflicts).
