I have a new LGOLED55B7 TV and a new Xbox one x which are running through an older ONKYO TX-SR606 Amp via an optical cable (As no ARC on amp). The Xbox is connected direct to the TV for visual and set up for optical bi-stream DTS on the Xbox settings. The ONKYO sound test produces sound through my 7.1 set up speakers in the correct manner for side and rear speakers etc however when playing sound through the xbox game or TV it only produces sound on the front speakers even though set to Dobly Pro Logic II. I have run a Dolby test via youtube as well and get the same results. Anyone know what I am doing wrong or need to do to get the setup to work? Do I need to tell the amp to run Dolby through the digital input button?
