HOW TO PLAY EAC3 ,TRUE HD

Method -1
There so many video players available but most of user favourite player is MX player .This player have so many features .
Go to Settings > Decoder scorll down to last choose custom codec and click open the file we provided below.
Now go to the player change the Decoder mode to SW or HW+ in the Mx player. Now you can enjoy the movie with Dolby digital plus (EAC3) And True HD ,DTS HD MASTER,FLAC all audio format now play smoothly.The disadvantage of SW decoder mode you cannot get original 5.1 audio the decoder change the audio to pcm 5.1 audios.

Method -2
The previous method is additional codec installation process but Kodi Player have inbuild Audio codec so we didn’t download any additional codec.but its still not support Eac3 audio why? We have to change one step to play eac3 audio support

Go to Audio Settings And disable the Allow passthrough now you can hear the audios from dolby digital plus but it’s also not true 5.1 original audios
