I have a question about the basic Dolby 5.1 functionality of my Vizio E65-C3.
I am using the Digital Optical Audio out (Toslink) to a Dolby Processor, and it appears that I'm not getting true Dolby 5.1 from the sources that support this.
The sources I watch come from the Time Warner App on a Roku Stick, along with the Amazon, Youtube, and Netflix Apps on the Roku. I have been using a DTS 5.1 Sound YouTube video, which is supposed to send a signal to each of the speakers, to test this, and have also used the THX Tune-Up Android App, through my Galaxy Note 3 via Chromecast.
When I'm testing output to the Left Channel, I hear it clearly in the Left Speaker, but also fairly prominently in the Center Speaker, and pretty much not at all in the Right Speaker. Same when testing output to the Right: I hear it both in the Right and Center Speakers, and not in the Left.
When the test signal is sent to the Center Channel, I hear it in Center, Left, and Right Speakers, pretty much equally.
This makes me inclined to think that I'm hearing "simulated" Dolby 5.1, rather than "true" 5.1. Am I correct in thinking that the various test signals should be heard *only* in the designated speaker, and *not at all* in the others?
I have run the YouTube test video via the YouTube App built-in to the Vizio TV itself, the one on the Roku Stick, and also the one built-in to my Bluray player (Sony BDPS-5500), which is connected via HDMI to an HDMI input on the Vizio (actually I think it's plugged into HDMI1 which has ARC capability). The results are always the same as documented above.
Listening to a Bluray, it certainly seems as if things are being processed properly from that Media: dialogue is strongly anchored in the center, and various effects can be heard in fairly distinct locations, although this is a subjective test. My question concerns the sound when it is coming from the TV itself, Roku, Chromecast, etc., many of which should be delivering true Dolby 5.1 sound.
I'm using a J-Tech Digital Audio Converter
, the output of which I send to a 4-channel amp/4 satellite speakers, and to a powered Center Channel Speaker. This is an inexpensive device (around $60), which doesn't show what type of signal it is recognizing.
So if I'm not getting true Dolby 5.1 out of the TV, I'm trying to determine if it's the TV itself, the Digital Optical Audio out (which is set to bitstream, by the way), or this J-Tech Digital Converter.
Those of you with this TV, is it able to output true Dolby 5.1 via its Digital Optical Audio out? With all sources, or only some?
Any insight to help me sort this out would be appreciated.
