I don't see make, model or mention of driver install, OS in use and if it did this when new so I'm left with only my thoughts. Tell more.
I use a USB connection for my audio. USB headphones ect. Randomly my left and right stereo channels switch mysteriously for no reason. So while I’m playing a game, suddenly my right audio will go through my left headphone. I tried switching headphones, same issue. When this happens, I can hear what seems to be a very brief “short” in the headphones like a static shock.
