I am in the process of upgrading my family room home theater system with a new television/Xbox Series X/Sonos ARC. We do a significant amount of online gaming and I am concerned about multiple blogs complaining about in-game audio lag with this setup. This appears to be an issue across multiple setups including non-SONOS sound bars. Before I spend a ton of cash I am wondering if there is an inherent problem with the console>TV>eARC>soundbar format with gaming specifically. I envision that there is limited ability to adjust AV sync with online gaming since it is quite important not to have a delay in either in this environment.
For reference my current set up is XBOX One X with audio directly out to Playbar via optical and HDMI to my television with no delay issues but obviously only outputting 5.1.
