Ok managed all of that and actually now most things work. However, cannot get sound. Have tried every device, restarted and no luck. I tried AUTO, CUSTOM, HDMI0, HDMI1, HDMI2, HDMI3, ACS...
Then I tried:
CTRL + ALT + F4
At this stage I had no idea what I was doing but pressing ‘,’ seemed to switch the 4 S/PDIF’s on. However I then have no way to seemingly exit this screen.
Any help appreciated!
