Does the TV you own have “enhanced HDMI” as an option?
This could possibly resolve the issue, as I know my PS5 wasn’t up to scratch as expected until I activated this on my TV.
There might be a solution in the Xbox forums as it’s been highlighted with different applications regarding the delay in sound.
Hi @Anonymous User
Does it happen to all NOW content you watch or just a particular TV show or movie ?
Are you using both HDMI and optical out from your Xbox to the same Audio playback device ?
If so what happens if you use optical out only ?
If the HDMI is passing through your television first and then going into a soundbar for example, what happens if you temporary unplug the power to the television for around 2 minutes.
I don't own an Xbox or any Games console, but i would also have a play around with the different sound and HDMI settings on your Xbox (even if other Apps are playing fine with regards to sound).
