Audio devices are recognized on this machine. The model number of his headset is Logitech G35. We originally used the headset driver but when we do, Roon does not play any music, it just skips from one song to the next, never playing any of them. So that is when we tried the Realtek audio which does not work at all. Not sure why it just skips from song to song and does not allow playback with the headset driver.
