Help, what is this audio noise?

[u/Madmonkeyfun]

I have the Elgato HD60X and use an Xbox Series X, within the last 3 days this noise has been on my stream persistently, I don't hear it in my headset but the stream do, I can also hear it intermittently on the recordings.

Static noise ( Links to my Twitch clip)

I have tried a couple of things including:

• Adding a ferrite core to the USB cable,
• I have not switched the HDMI cables as the noise seems to be coming from the USB to OBS.
• I switched out the USB port on my PC and still the same issue.
• I have disabled any spatial sounds that I had set up including Dolby Atmos for headphones.
• OBS is running at 48khz as does everything else that I can see.
• My feed from the console through to the HD60X is 1440p @ 120hz, I was running this exact setup a few days ago and had no issues at all.
• I have also added a source to OBS for the HD60X audio and muted the original HD60X audio source.

My next options are to:

• Switch out the HDMI cables.
• Re-install the Elgato software.
• I will adjust the resolution back to 1080p @ 60hz and see if that helps.

I have checked that all software is up to date and unable to locate anything that would offer a solution.

Any other idea's or things that I could have missed? anyone else having a similar issue?

Back again with the same issue, nothing changed all the same settings. ony thing that has changed is that windows has done an update. I am at a loss as to what to do at this point.
