Volume Normalization

[LordMelvin]

Sorry to be a couple months late, but for posterity, what you are describing is a textbook case of not mixing a film or show's surround mix down to stereo properly. Surround sound mixes usually put almost all dialogue in the center channel with very little dialogue, but plenty of music and sound effects placed in the left and right side channels, and the left and right side channels will be the default two chosen by a discarding stereo implementation, where the player is accepting all audio channels from the server but then only feeding 'stereo' to the actual speakers.

The fix for this should be, on your device, in 'user' 'settings', under 'playback' assigning 'Maximum Allowed Audio Channels' to stereo. This should then ensure that the server is properly asked to downmix to stereo, with whatever downmix settings you have in place there.
