Running Sierra with an MSI GTX 760, audio works through front panel headphones however monitor speakers are not working. When looking at output devices, monitor is not displayed. Tried running the cloverhDMI120 script, says that no HDMI audio codecs were detected and when asked if it should install AMD/Nvidia codecs, it then says no discrete card found even though I am running my display through my 760. Any help will be appreciated. Here is the full output:
