This problem started few months ago after I updated audio drivers to my Asus Rog Strix x470-f motherboard. Until then the audio was working just fine but after I updated drivers, for some reason I can't get the rear panel to work. If I plug any audio device into front panel audio jack it works just fine but whenever I plug it into rear panel it doesn't work no matter what I do. I solved this by just completely unninstalling the audio driver from my PC and ater that, it works fine. The problem is that once in a while I get a blue screen which according to my research might be related to driver issue, so I am trying to update all of them, but when I update the audio driver, the rear panel stops working.
