Set top box sending Dd5.1 with depopulated center and/or surrounds
I’ve got a sound bar with a dedicated center channel. I’ve come across a bunch of channels in my FIOS sEt top box that appear to be outputting DD5.1 but the center channel and surrounds channels are often not there leaving me with a muffled, no vocals, bad experience. So I ended up setting the audio output setting to PCM. Any ideas what’s going on with this?
