MX Player Support DTS and AC3 Audio using Custom Codec [Fixed]

MX Player comes with tons of features and is a must-have app on any Android device. It lets you play any video file whether it is an HD, FHD, or 4K with high-quality sound. Additional gesture support makes using this player for video a treat. It is one of the features that was unique about the MX Player.

However, the MX player does have some limitations and one of the biggest issue with MX Player, both free and paid, is that the player does not support ac3, eac3, mlp, and dts audio natively.

In the recent versions of MX Player, the company officially removed DTS & Dolby audio codec support from their much-praised video player for Android. Therefore, if your video has dts, dtshd, ac3, eac3, or mlp audio tracks, the MX Player will not play any audio. Instead, you will get a popup message saying that only the video is playable.
