I have no audio at all since I installed the latest update. Both the display port and hdmi dont show on my audio devises. I already tried uninstalling my digital devices connected and nothing. I cant reinstall drivers for hdmi and display port cause they dont even show on my device manager. and they are connected. I can see both just fine. Just not hear them.
There are a number of reports on this.
Clean install the previous driver and wait for a patch.
