When I record a video it always have no sound I don't know why?

I don't have an answer, but I do have videos with and without sound. After my "Record That" prompt, the resulting 30 second DVR clip has sound. When using the DVR's Start Recording feature to record and edit a 2:49 video, the audio is not present.

I don't see why you'd have to switch inputs to watch recorded stuff, I mean surely all that's going through the console is the audio/video I'd have thought. But I don't know the ins and outs of HDMI's capabilities.

My computer is a dual graphics, I for the sake of better performance, was shut down a collection of CARDS, with an independent video card, and then I can't record the screen's Xbox, win each use R Alt displays can't recording, I don't know why, but I have
reopened double graphics can be recorded, but I'd like to have

i know this is stupid of me but

since i have a similar problem i always record my voice later by replaying the video gameplay i did in my video editor

Thank you for answering. Yes, I checked that article already, and that particular suggestion too. According to it checkbox should be checked to avoid problems, and it is checked while I try to record, so it's not working. I tried the other way too - same.
I also tried to change other options like FPS, video quality, record during playing. The latter for whatever reason records only the very first 21 seconds of gameplay, even on consecutive requests to record a recent fragment, it's always the same 21 seconds,
even though it creates different video files.

The only thing I managed to do is to record up to 40-45 seconds by decreasing video quality and disabling sound recording completely. And I think it may have something to do with RAM usage? Maybe? I don't know. And it brings us back to original question.
What is code 2184327175 is about? Someone from Game Bar developers team should know!

Also worth mentioning that recording of "non-game" desktop applications works with no problem. I can record Firefox for minutes and it saves video without failing (didn't try it for more than couple of minutes though).
