I have a 2019 Sony XBR A8G connected to a Playbar (paired with two play:1s for 5.1) via optical cable.
Whenever the source audio is Dolby Digital, there is a slight delay in the audio and is behind the video. When I override the audio to stereo or PCM, either through TV settings or source device (Amazon 4K Firestick), the audio syncs up perfectly.
This leads me to believe that the lag gets introduced by the Sony TV when it “passes through” the Dolby digital signal to the playbar.
Has anyone found a fix for this through the TV’s settings? Sony support isn’t very helpful. Potential workaround is an HDMI switch to split audio before it gets to tv, but not sure if that’ll introduce other headaches.

Got the hdmi switch today with optical out and it worked like a charm. I actually had the opposite problem where the audio was ahead of the video, but that’s easily adjustable within the Sonos app and is now synced up perfectly according to my overly discerning eye.
No other major headaches that have come with it other than a few more wires to contend with behind the TV.
Still disappointed that Sony hasn’t figured this out and will be expressing it to them. Ultimately, an extra $50 for the switch is a drop in the bucket on a $3,000+ entertainment system, but I probably spent a solid 10 hours researching and troubleshooting. This felt like a problem I would have grappled with 15 years ago but surprised me it’s still an issue.
Thanks for your help! Your responses to some other posts have helped me troubleshoot a couple other issues as well :)
