One of the most popular and feature-rich media players available for Android devices is MX Player. However, users sometimes encounter an issue when trying to play high-quality audio formats like AC3, EAC3, DTS, and Dolby TrueHD. If you’ve ever seen an error such as “This audio format (AC3) is not supported,” rest assured—you’re not alone. Fortunately, you can solve this issue by downloading and installing the MX Player codec, especially the AIO ZIP file, which brings back support for these advanced audio formats.
Why Do You Need MX Player Codec?
In recent versions, MX Player has removed support for certain audio codecs due to licensing issues. As a result, formats like AC3, EAC3, and DTS are no longer natively supported. Without these codecs, the player can handle video but won’t play the audio correctly—or at all. The official solution is to manually download and install the necessary additional codec packs.
The most efficient way to resolve this compatibility issue is to install the MX Player AIO ZIP codec, which is an All-in-One codec package that supports a wide range of audio and video formats including:
- AC3 – Dolby Audio Codec
- EAC3 – Enhanced AC3
- DTS – Digital Theater Systems audio
- MLP – Meridian Lossless Packing used in Dolby TrueHD
Types of MX Player Codec Packs
Before we walk you through how to install the codec, it’s important to know that MX Player offers different codec versions based on the CPU architecture of your device. Here are the most commonly used ones:
- ARMv7 NEON
- ARMv8 NEON
- x86
- All-in-One (AIO) ZIP
Instead of worrying about matching the CPU version of your device exactly, many users prefer to download the AIO ZIP version, since it includes support for all processor types in one package—thus avoiding compatibility issues.
How to Download and Install the MX Player AIO Codec
Follow these simple steps to download and integrate the AIO ZIP codec with your MX Player:
- First, check your CPU architecture by using apps like CPU-Z if you’re downloading just a specific codec version instead of the AIO ZIP.
- Download the latest MX Player AIO ZIP codec from a trusted source or the official MX Player site if available.
- Open the MX Player app on your Android device.
- Navigate to Settings > Decoder, and find the option that says Custom Codec.
- Tap on “Custom Codec” and locate the ZIP file you downloaded to your device.
- After selecting the file, MX Player will automatically restart and integrate the new codec.
Once the codec is installed, test by loading a video that previously failed due to unsupported audio formats. You should now be able to hear the audio clearly in full surround sound quality!
Benefits of Using MX Player with Custom Codec
Installing the AIO codec file greatly expands MX Player’s capabilities. Here are just a few benefits:
