Everytime my computer comes out of Hybrid sleep, I have to uninstall and reinstall the HDMI audio via Device Manager. Sometime HDMI audio disappears or is occupied by another source. Only way to get HDMI audio to work again is by uninstalling and reinstalling the driver. This only happens after coming out of hybrid sleep and using Hotfix 16.1 driver. AMD 15.12 driver doesn't have this problem. opened a bug note to AMD to let them know.
