I have an R5 2600 and an ASUS Prime X470-Pro board. I am using the Realtek audio drivers downloadable from my motherboard's driver/support site. My front panel audio is working, but my rear audio is not. I hear sound for a split second when I first plug the headphones in, but then sound stops altogether.
The odd thing is, when I unplug my headphones from the rear, Windows notifies me, but when I unplug my headphones from the front, Windows is silent about it. I am thinking that maybe my sound is still trying to play from my front panel for some reason??
