So I have been setup for a number of years with Openelec and then LibreElec, feeding HDMI to my TV, and passing audio back to my receiver for sound with no problems. I just switched from an LG plasma to a Vizio E60-C3 TV tho, and, changing no settings in LE, I get all the audio EXCEPT the dialog. There are two TV audio output settings (Bitstream and PCM), and neither one seems to make a difference.
The only way I can get the dialog is to change the number of audio channels in LE from 7.1 to 2, which kind of defeats the whole purpose of a home theater system.
The only change I made was the physical TV. No software or other changes.
OE -> TV via HDMI -> Audio out from TV via optical to receiver
Note that I do NOT have any HDMI ports on my receiver. I have passthru audio off in LE.
Any ideas what I can do here to get surround and dialog back?
