Initially i set pcm my sony tv displayed all as stereo. After i set bs out my sony tv displayed as stereo for aac n dolby digital for dd+.
DD is very loud while DD+ is soft but still clear.
The HDMI is actually an intelligent interface that support automatic configuration, it allows the transmitting source (STB) to automatically deliver the most effective format (e.g. DD vs 2 ch PCM) for the TV receiver that it is connected, eliminating the need for user to scroll through a list of audio formats. Thus, it is strange that the box's HDMI output actually follows the BS Out settings….. there could be some limitations in the main chipset, or even a software bug.
Your Sony actually detects DD, this seems to indicate that a DD+ decoder by default, has a DD+ to DD transcoder. What is left is whether the box converts HE-AAC 5.1 to DD 5.1 and presents it to the Digital Audio Out. Both cases can simply be verified with a DVD HTS.
