For the past two days not I haven't been able to get audio output from either one of my two monitors. The only way for me to get audio is through my headphones connected via USB. Both the monitors are connected via displayport. I've set my monitors as default device in the sound settings with no luck. I've also updated my audio drivers and updated windows to see if that was the issue but still get no audio. Are there any suggestions as what else I could try.
