Sound lag on Xbox series X and sound bars

I'm going off that the OP was going to connect the Xbox to the sound bar then the sound bar to the TV, this route would require the sound bar to have HDMI 2.1 to retain 4K at 120hz for the TV

"If I hook up my series x to sounder and sounder to my LG CX"

"So if I pass the xbox through soundbar to tv, not sure if I will lose some of the features (VRR, 4k 120FPs, etc)?"

If they can connect the Xbox straight to the TV then the TV connects to the sound bar, they should be fine and everything works.

Same issue here.

I’ve got my Series X hooked up to a brand new LG C2 using the HDMI cord that came with the Series X.

I’ve got an Atmos-enabled Vizio sound bar (5.1 + two height speakers in the sound bar) hooked into the TV’s HDMI-Arc port.

I have no issues with Atmos sound when playing games on Series X. I have no issues when watching Atmos-compatible movies in streaming apps like Apple or Disney+.

But, when I play an Atmos-enabled 4K Blu-ray Disc on the Series X blu-ray app, I get this weird audio buffer after a few minutes. The movie may go 20 minutes without, but once is starts going it gets more consistent. This issue persists regardless of which Atmost-enabled 4K Blu-ray I use.

I’ve tried messing with the settings - switching back and forth on allowing pass through, etc.

Funny thing is, on my older TV (a TCL Series 6 which was not VRR or 120 hz compatible) I had zero issues. My Series X would play Atmos 4K blu-rays no problem. Only difference I can think of is that on my old setup I hooked the Series X directly into the input of the sound bar and then output from the sound bar into the TV (it was the only way I could get Atmos to work on the old TCL Series 6). On my current set up with the LG C2 I don’t do that because passing the Series X through the sound bar would take away the VRR and 120 hz capabilities my new TV can do.

Can anyone help?

If i conect my soundbar to my tv instead of directly to my xbox one s the audio dont sync righy thats why i comect it to the xbox directly i think that will be the same when i get my new console i dont know i guess ill figure something out somehow

I also have the same setup. Xbox Series X conneted to Samsung TV via HDMI. Samsung TV connected to a Klipsch sound bar via HDMI ARC. Experiencing the same issue described by many others.
