It's clearly flailing.
Me, I'd connect my Beagle 480 USB hardware protocol analyzer.
I can't tell, does this support analog headphones in an adapter plugged into the Type C connector?
Or does it have a separate headphone jack?
The reason I ask if it it has analog over Type C then there is an additional multiplexor inline with the USB data.
That's another possible point of failure.
It looks like were talking warranty repair.
