I have just purchased an Odyssey G8 monitor (G85SB), when I plug in headphones, the unit still uses the speakers, when I open the sound settings to change this, the sound comes through the headphones, and the config looks fine, as soon as I close the settings menu the headphones stop working and the speakers resume again. So I know the headphones are fine, the unit is just not accepting the settings.
I am using my PC linked to the unit via HDMI.
I have done the software update etc so it is up to date.
