My tv is consistently 30 seconds behind when watching, which is most obvious on live sports. Incredibly annoying, especially for the price I am paying. What do I need to do to fix it or I am going to have to switch services.
You can log into your Cox account to reset or refresh...whatever their term...your cable-box. I'm not suggesting it'll resolve your problem but it's an action nonetheless.
After you've done everything a customer could do, then you can escalate to Cox. Perhaps it's the node servicing your neighborhood. Any Cox customers in your neighborhood with the same sync issue? If not, you can swap your box. I'm trying to avoid a $$$ tech visit.
