PCM vs DD - why DD is louder in a 2 channel system ?

I am using a Song Blu-ray player that is hooked up to a DAC thru a SPDIF coaxial cable (then DD is downmix to a PCM). So this is a 2 channel playback.

When I play a blu-ray disc which has both a PCM 5.1 track and a Dolby Digital track, the PCM option sounds not as loud as the DD option. In fact, the DD option sounds much louder & clearer. It is like something is missing from the PCM playback.

Is it because I have only 2.0, so the other 3.1 is deleted thru the transmission ^_^ ?
