About EAC3 Audio Support in MX Player

EAC3 is an audio format developed by Dolby Labs as the successor to AC3. It is primarily used on HD DVD and Blu-ray Discs to provide cinema-style surround sound. Many movies you download these days come with EAC3 audio in MKV format. However, when you try to play such videos in MX Player, you may encounter the problem that only the video plays but no sound. You will see an error message like "EAC3 is not supported".

This happens because the player lacks the EAC3 codec used to decode EAC3 audio in the video. In fact, MX Player previously removed a set of codecs from its codec library, which included DTS and Dolby Audio, such as DTS, DTS-HD, EAC3, and MLP. If the video contains any of the above audio codecs, you will not be able to play the video properly. Fortunately, there are many ways to solve this problem. Here we'll cover the best three methods.
