I'm unable to send screenshots at this time, but with every combination I received The exact same error depicted by SpoopyJilan. Thank you for doing this, Much appreciated!

On the website for this soundbar it lists that the bar has HDMI in and out, as well as optical in.

In order to find out where the drop outs happen (it might even be an incompatibility with your TV and ARC, where the TV is sending erroneous data via ARC to the soundbar), try the following test scenarios:

Connect the Xbox to the HDMI in port of the soundbar, and check if the soundbar can relay the video to the TV via HDMI out (if necessary, in standard 1080p instead of 4k, just for this test).

Additionally, try to connect the console to the soundbar via optical TOSLINK cable, and use Bitstream via optical cable to get surround sound from the soundbar.

If the drop outs disappear when the console is directly connected to the soundbar via optical cable or HDMI in instead of ARC, your TV might be the culprit.

As for the "best" setting:

Using Stereo uncompressed only gives you left and right channel audio, as if you only had two speakers.

With Dolby Digital and DTS you at least get surround sound where sound could appear to come from behind you.

I don't know how the Virtual: X from DTS works (if it's upscaled from a "standard" DTS signal, or requires a native DTS:X signal). However, if your TV's ARC doesn't support the 3D spatial sound formats DTS:X or Dolby Atmos, you would be better off connecting
the console directly to the soundbar via HDMI, and letting the soundbar forward the video signal to the TV.

Have you tried using an optical cable from your TV back to the Soundbar? Connect your Xbox One via HDMI to your HDTV then use an optical cable from your HDTV to your Soundbar. Does that work?

The Xbox One X doesn't have a soundcard, in a way a PC would have a Creative Labs SoundBlaster card for example.

The Xbox One does all sound processing on the main CPU so to speak.

However, the clearer sound when you connect the Xbox to your soundbar directly can have other reasons than the "soundcard".

I assume you had your soundbar, TV and console set up like this:

Xbox One Console-->HDMI Cable-->TV-->Optical Cable-->Soundbar.

While the console transmits multi-channel surround to the TV, the TV might only transmit Stereo to the soundbar.

A lot of TVs only forward Stereo Sound through an optical cable, if the video feed comes from an external source. Only "internal" video streams that come from the TV's own tuner or media being played through the TV's USB Media Player will be transmitted
in multichannel audio to the sound bar.

By connecting the Xbox directly to the soundbar, the soundbar will get the original multi-channel sound from the console, instead of the stereo downmix from the TV.

So I assume your setup now looks like this:

Soundbar<-- Optical Cable<-- Xbox One -->HDMI cable--> TV

Right?

I just have the soundbar connected to my tv via optical cable and my xbox is connected to my tv via HDMI.
