Problem with sound from center channel
At my home I have recently set up a 3.1 system and I'm having issues with getting sound from my center channel at times. I would like advice on what I can do to get sound from the center at all times.
Here is my current setup.
TV is Samsung NU8000
L/R Tower Speakers Martin Logan Motion 20s
Center Def Tech 9040
Sub-Woofer ML Dynamo 500
At this time I am streaming everything from TV shows and movies on a firestick or via the apps in the Samsung NU8000 operating system. Music is streamed from Apple Music on my phone. Here is what's happening.... I stream from the TV app store Netflix and Amazon Prime Video and everything works perfectly!!! If I use At& T Now App on the TV it seems to only play in 2.0. Apps I play on firestick are 2.0 and Music via Apple Music are 2.0. Is there at setting I need to been in on my Denon receiver so I can have 3.1 all the time? Or does the issue have more to do with the source only being transmitted in 2.0?
A few years ago in another home I had a 5.1 setup with different speakers and it seems the center channel was always working with no problems. Any advice you guys can provide would be greatly appreciated.
