I have a Sony STR-DE997 7.1 receiver and a older 70" Vizio LED E700i-B3, connected via Digital optical cable. I have Frontier Fios STB, Apple TV, PS4, and Nintendo Switch connected to the TV using HDMI.
Since the battery on my UPS died (not sure if this is coincidence or not), I haven't been able to keep the sound in sync with the video. It seems to happen on all devices. I couldn't find anything online to help, Frontier FioS had me adjusting the sync delay on the TV, but that didn't stay. The only thing that seems to work is to turn off the receiver, and turn it back on; but that is only temporary.
Do the Digital Optical cables go bad? Any idea how to fix this delay? I've been struggling with this for months.
