    I'm experiencing a consistent audio synchronization issue (the audio is about half a second behind the video). The delay can be reduced by setting the output to PCM, but it happens consistenly when the audio setting is Dolby Digital.
    This started happening several weeks ago - nothing had changed otherwise.
    My tivo (roamio pro) is connected to my TV via HDMI, and the TV connects to a soundbar via optical. My TV is a TCL Series 6 Roku and my sound bar is a Vizio 5.1.

    Do you get the same thing if you disconnect the TV output to the soundbar and just use the TV speakers?

    Have you tried tweaking the sound delay in the tv audio settings? You usually can adjust them a few milliseconds either way to tighten it up. It hasn’t been a problem with my Samsung tv but I had to tweak it for my Vizio before.
