Lip Sync with Fios STB (VMS4100)


Hey Verizon,


I have a new Fios TV installation and there is an audio delay issue from the STB when Dolby Digital 5.1 (surround) Audio Format is selected.

Switching to LPCM (stereo) Audio Format fixing the issue but I did not sign for the TV service to hear the channels in stereo on my home theater setup and definitely not to watch them with annoying lip sync issues.

The delay happens in both HDMI and OPTICAL outputs from the STB.

Just to clarify, the audio stream is being sent with a delay and lagging the video stream, which means that the "Audio Delay" function that is common in the various devices can't help.


Please provide a solution and by solution I mean something serious and not the: "replug the power", "reconnect the cables", "try different cables", etc.
