Subject: [PATCH 17/17] mlpdec: support TrueHD streams with an Atmos substream
The fourth substream is being discarded, since its not raw audio data,
but an encoded Atmos stream which needs a specialized decoder.
Fixes decoding of the true hd stream from Transformers\ -\ Age\ of\ Extinction\ 2014\ 1080P-003.mkv
