Top 3 Remedies to MX Player EAC3 Not Supported Error:

Before anything else, here is something you should know about EAC3. EAC3 is an audio format developed by Dolby Labs as a successor to AC3. It is mainly used in HD DVD and Blu-ray Discs to provide theater-style surround sound. Today, many movies you download online come with EAC3 audio in the MKV format. However, when you try to play such videos in MX Player, you may face the problem that there is only video playing but no sound. You will see an error message like ‘EAC3 not supported.’ This occurs because the player is missing the EAC3 codec for decoding EAC3 audio in the video. In fact, MX Player removed a group of codecs from its decoder library before, which includes DTS and Dolby audio like DTS, DTS-HD, EAC3, and MLP. And you can’t play the video properly if it contains any of the mentioned audio codecs. Fortunately, there are many ways to fix the problem. Here we will introduce the best three methods. Let’s go for the details below.
