I have searched for other people having this issue but can find any similar stories.
I am not getting Dolby 5.1 surround on any of the services when I stream media (Netflix, Vudu, Hulu, Amazon, HBO Go, and XBox video). This has been happening for quite some time. My receiver (Denon AVR-1610) indicates that it is receiving a Dolby Digital signal ( and when "status" button is pressed says signal is 3/2/.5) - but I get no center channel or sub woofer playing. I believe there are no rear surrounds either.
Thing is, it doesnt sound like it is simply in stereo, because the front speakers are very quiet and i need to jack up the volume to hear the dialogue. Other strange thing is that Dolby 5.1 works perfectly in the dashboard and in games. It is only when I click over to one of the apps that it shuts off. It has done this across the board, even on brand new releases and tv series.
I have the XBox 360 connected to the Denon via an HDMI cable. I have tried different cables and different HDMI inputs on the receiver with no luck. I have no problems with the surround sound (or speakers) when connecting a Blu-Ray or my Zotac media PC. Those sound awesome.
It is unfortunate because I use the streaming services so much but the sound quality is frustrating. Oh, I have tried setting the XBox audio settings to both "Dolby 5.1" and "Dolby 5.1 w/ WMA" also.
