Xbox Atmos Lag

Arora87

So I recently purchased a Samsung N950 soundbar and when I enable the Dolby atmos feature through xbox one x I get an audio lag in my sound. It's a less then 1 sec delay on YouTube, Netflix, gaming and actual 4k blu ray movies. I've tried both the lip sync feature on the soundbar and my LG C7 but that doesn't solve the problem. I've played around with the wires, tried different hdmi wires and connections. Cleared cache on the blu ray drive, and I even went to Microsoft and they were nice enough to replace my entire console. Same issue. When I switch to optical or non Dolby atmos the sound works fine but you lose on the sound immensely and it defeats the purpose of having atmos. But once i install Dolby access and use Dolby atmos, the issue arises. I have cable TV, and apple 4k tv and have no issues with sound on those devices, only xbox. I've called Samsung and xbox support and they've had me try a bunch of things but nothing works. Samsung says it's not there product that's faulty it must be the xbox.I'm not sure if it's a software patch that needs fixing or if my soundbar just won't be compatible with the console. I've read other forums and notice Dolby atmos issues with all sorts of atmos devices so I guess it's not just Samsung. Was hoping to see if anyone had any more tips or advice for the issue. I'm not sure what to do next. Thanks. Hopefully someone can help.

Sorry I don't know what to suggest but my guess is your Samsung N950 doesn't get on well with the Xbox One X wrt Dolby Atmos. I say this because I recently purchased a Sony X8500 sound bar (Atmos equipped) and it works very well with my Xbox One X through the Dolby Access app and no issues at all.

Psychopomp1 thx for the info. I'll try returning this soundbar to a new one or different brand and see if that works. Probably the only thing I haven't done at this point. Cheers ..

Did you connect the Xbox directly to the soundbars HDMI input, if no try that instead.

HDMI-ARC is reliant on DD  Atmos, LG TV's are known to have sync issues with Dolby audio over ARC, but when going through the soundbar HDMI out the audio format should be Dolby MAT (PCM   Atmos).

Samsung also have a firmware update for the soundbar.

If you did try direct connect via HDMI already and it still was laggy then replace the bar with another brand.

Next010 I just tried this and the hdmi1 connection had the same lag. So you think I got a defective soundbar or just an unfortunate compatibility issue with the devices? I may take the advice and try a different brand. Thx for the help.

is the xbox one connected to the soundbar directly? using ARC and bitstream causes some delay. I have this issue with my Samsung tv and LG soundbar, but if I run my xbox through the soundbar with bitstream enabled the lag isn't there, or at least greatly reduced
