No browser video/usb audio playback, Audirvana not allowing play.

After a successful install of High Sierra on a x570 Strix I/ 3700x/Vega FE system, I am unable to play Youtube videos (prompted to restart my "device"), or any online video/audio, and using my purchased copy of Audirvana, I only see the app loading the songs, but no movement/playback tracking in its GUI. I don't have these issues with my Intel 'tosh. Audio out is USB to DAC, or through the dual Cinema Displays, though no audio even through the displays when attempting to use non Apple players. USB DAC is selected as default audio output, but no sound is heard, except through the monitors when they are selected. None of these issues on the Intel hackintosh...any suggestions?
