This problem is widespread, especially with files sourced from streaming platforms (like Amazon Prime, Netflix rips, or modern Blu-ray remuxes) that use Dolby Digital Plus for surround sound.

This article will explain why MX Player struggles with EAC3, the technical background of the codec, and—most importantly—seven proven solutions to fix the audio problem for good.

The most practical solution is the installation of a custom FFmpeg codec, which restores EAC3 playback via software decoding. For users unwilling to modify their player, switching to VLC or transcoding the audio track provides viable alternatives. As audio technology evolves toward object-based and immersive formats, media players must adopt modular, licensable decoder frameworks to maintain compatibility without compromising legal compliance.
