ATV4------HDMI audio splitter--------TV
|
YAMAHA YS105(only support Dolby 5.1)
When I play a HD7.1 movie ,It seems only 5.1 have been played , it have loss 2 channels ,it sounds strange.
I have set the ATV4 on 5.1
In mrmc
Number of channels-----------5.1
output configuration-----------Optimized
stereo upmix--------------------On
Maintain original volume on downmix-----on
engble passthrough------------On
dolby digital capable receiver----On

Is there any settings wrong? How can I get all movies played in the 5.1 dolby.

if you want 7.1, set channels to 7.1
