Atmos files cause problems for most e2 boxes. In theory a player that doesnt support Atmos should be able to play the TrueHD core track - while most bluray players are capable of TrueHD its not a format supported by most satellite boxes. The specs show bog standard DTS as the highest format supported. As there are no DTS core tracks in an Atmos track an e2 player cannot handle the stream and generally results in stuttered playback at best. My SF8008 can handle most of the stuff I throw at it but I have an old android box kept in a drawer which runs librelec and can pass through the TrueHD tracks perfectly.
