I have a gigabyte x470 ultra gaming 7. And when I have my Logitech Z623 speakers plugged into the back 3.5mm audio jack they sound really quiet turned up to full volume. Now this problem just started recently. Like the speakers worked perfectly fine a few days ago then all of a sudden they started doing this. when I plug the audio jack into the front of my tower they work fine. I'm not sure whats going on.
