Why can I adjust the sound lag in the wrong direction but CANNOT improve it on tv surround setup?
Between the Sonos adjustment and the Samsung OLED, I can only make the problem worse.
I waited years to pull the trigger on this setup and (in my wife's words...) "ITS UNWATCHABLE"
The Sonos lag can only be increased. It’s not possible for the Sonos App to play audio before it receives it.
You don’t have a soundbar mentioned in your profile, can you confirm what Home Theatre Sonos device you have connected to your TV?
My surround setup is:
Arc Gen1
Sub Gen3
ERA 300 Gen1 (pair)
I have set TV dialog sync to 0, group audio delay to (min) 75ms, and on the TV (Samsung OLED) I have done the same.
The delay is substantially more than 75ms
I have the same Sonos setup, but with an LG TV, and Sonos App settings and don’t get any audio lag. Are you using an external source to the TV?
Yes, TV source is Xfinity.
Also, I miss spoke. The TV IS the LG OLED
I just tested it on wifi with Netflix and it is a noticeable improvement. So, the issue is with live TV on wired cable feed.
It's so odd
A quick search suggests that you turn off Secondary Audio Programming (SAP), please see:

Sorry, if this is something that you have already looked at.
I've tried everything. NOTHING works
So frustrating. Hindsight is 20/20. 🙄😕
...at least music sounds good
Complain to the tv manufacturers. They need to introduce a “video delay” feature. Many soundbars suffer from the lag you’re experiencing.
In my experience TV voice sync varies from program to program. I’ve been in a TV station central control and voice sync was already out of wack. When I pointed this out, I got a blank stare indicating that I “didn’t get it”.
The movie industry had this issue solved by the early 1940’s. In general I notice that voice sync is better on movie channels.
