Hi Can any Technical Expert Suggest me i have purchased Yamaha 5.1 Home theater and i have a samsung Blu ray 5.1 . My concern is little complicated all physical connections are fine. The major issue is if i play a blu ray and want to hear the Sound effect from the Yamaha 5.1 i hear only the vocal and if i play the Hard drive through the USB samsung 5.1 again i dont get the full bass and dolby digital sound but i hear from the samsung 5.1. Tried enhancing the Speaker configuration through HDMI 1 which is again the blu ray connect and optical is connected between both the samsung and yamaha 5.1 . The real out put what i saw & heard during the product purchase display am not getting the same here please do share the right method to get the best out put.
