Live TV issues, both audio and video

Here is another post that I wrote up earlier but didn't post:

Ok, I'm a little confused. Just to be sure, what is not working when:

1. Does the game audio work when the Xbox is directly connected to the TV?

2. Does the game audio work when the Xbox is only connected to the Headset?

3. Does the game audio work through the headset when the Xbox is connected to both the TV and Headset?

4. Does the game audio work through the TV when the Xbox is connected to both the TV and headset?

Note, the headset contains two different audio channels, when connected to the controller, you are receieving the Chat channel, when connected to the Xbox you are receiving the Game audio (the same that would go through the TV). The settings on the Xbox are
for Chat audio only. That should be set to headset only for when using the headset, this will cause game audio to play through both the TV and Headset while Chat audio through the headset only, if set to both game audio remains the same but Chat audio will
play through both, and of course of set to speakers then game audio will still play through both but chat audio will play only through the TV. Ideally, this should be set to headset only especially when using the X12.

As for the issues with sound, if it is your TV not producing the sound, check the settings on the TV. Make sure the connections are appropriate. You said you are using Composite, that means the standard Yellow video cable should be connected and the Red and
White audio cables need to be connected to the corresponding audio for that Video cable. Some TVs, such as my family's still strong Tube TV have 3 auxiliary sources all of which use the Composite Yellow Video cable. Make sure, if you have multiple inputs for
video, that the audio cables are connected to the correct coresponding source. For example, your TV may have Video 1 and Video 2 but if the video is connected to Video 1 and the audio to Video 2, then you will receive only Video when on Video 1 and only Audio
when on Video 2.

I'm sorry if any of this is redundant or obvious for you but the first part of this message (the 4 questions above) will better help me in assisting you further. Otherwise I'm slightly confused as to what your second post is saying. As a note, when I say game
audio, test out a game to be sure. Check to make sure volume is on on devices as well.

Hey sparks -

Sorry to hear about the issue. Do note that the
home theater setup guide does mention that this kind of basic setup with an A/V receiver, you're passing both audio and video through another device. Depending on your equipment, there's a small risk of audio or video lag. With that in mind, what is the
make and model of both your soundbar and TV? It's possible that one (or both) of those isn't able to handle what the Xbox One S is outputting and is trying to compensate which is causing the audio lag.

Keep us posted!

Well, the HDMI works on both audio and video, so I'm wondering why are you using optic link with an HDMI? Try to connect the HDMI cable directly to the TV and see if you get audio and video. I don't think it's an issue with your XBOX but I do think there
is one on your HDMI port on your TV if all you are getting is video.

Don't do it. Multiple issues with audio and video and there is not a timeframe fix available from Microsoft. Just read the live tv forums.
