VLC media player, Download For Android, Windows, MAC. I personally use VLC. You can also use MX-PLayer but MX-PLayer not supported EAC3 Audio File. So if you have to listen to a good quality audio such as Dolby Digital 5.1, my advice is to use VLC.

DD5.1 means "Dolby Digital DD5.1". If you have a speaker with Home Theater 5.1 and above, then you should use the DD5.1 audio. Two speakers in Home Theater 2.1, usually included a left and right channel and a subwofer. Five speakers in a 5.1 soundbar, usually front left, front right, front center, around left, around right, and a subwagher.
DTS stands for Digital Theater Systems. The main difference between DTS and Dolby Digital is seen in the bit rates and compression levels. DTS lossless quality compression audio.
