Video Lag on Xbox Live when Visio Sound Bar hooked up

After reading some other forums, I changed the Video setting on the Xbox One from "Auto-detect" to "HDMI." After doing this, I was able to select "5.1 uncompressed" from the audio menu on the Xbox without getting an error. However, at
this point, I was getting no sound. After a few hours of frustration (I thought it might be an HDMI handshake issue), I decided to hook my Xbox One directly to my sound bar via an extra HDMI input on the sound bar and then hook the sound bar up to my TV using
my HDMI ARC input. I now have surround sound!

The downside is that when I switch HDMI inputs on the TV, I have to switch inputs on the sound bar as well. I thought the promise of ARC was that the TV would act as the switcher for audio.

I won't complain at this point, but any thoughts on why I would need to hook the Xbox One directly to my sound bar for surround sound to work vs. hooking the sound bar up to my ARC input? When I didn't have a direct HDMI connection between the Xbox One
and the sound bar, I could get stereo uncompressed sound just fine. Is it a limitation of the TV? Could it be an outdated HDMI cord? Any thoughts appreciated.

I've got my 360 hooked up to the tv in on the xbox one. I have my Xbox one hooked up to a sound bar and a 60" T.V.

I tried what you said, and It didn't work. I've tried shutting down everything and restarting. Nothing. I have a sound bar hooked up to the optical audio, and that doesn't match with video, or the sound coming out of tv either.

I have the vizio S4251W-B4 5.1 sound bar hooked up straight to the xbox one using digital optical audio cable. Volume up and down command works for me. This sound bar supports DTS.

The Turtle Beach adapter will solve this problem. It basically splits the HDMI signal into optical audio and HDMI video.

HDMI carries both audio and video, so the Turtle Beach adapter basically helps give you the audio connection separately. It can also be used to hook up a sound bar or surround sound system (what i have).
