I've just installed a Z370 Extreme 4 mb with i7 8700k. I have troubles with front panel audio. Connected my case panel to the board audio connector, when I put an headphone in the jack windows detects it, but volume is loooow. If I put the headphone in the back green connector it's detected as an headphone (realtek tool shows an impedance scale) and volume is good. I've tried different headphones, and also changed the front panel: added a unit with usb and audio connector in the case so I've a new set of front audio jacks, but the headphone audio volume when taken from the board hd audio connector is always unusable (low). In Bios I've hdaudio selected too. Any help?
