In Windows 8 I had no issues with audio when resuming from sleep. My PC is connected to the receiver with hdmi then from the receiver to the tv. In Windows 8.1 if I resume from sleep the audio device is gone and I can only restore audio by restarting the pc. I am using the 15335 drivers which are the most recent. ANyone experiencing this behavior with Win 8.1.
I have the i3-4130 with the HD 4400.
