Hi All. I'm running a 2010 mac Pro 5.1, Pro Tools HD Native ( PCIE ) with a Blue face 192 interface. It's been running fine on Yosemite for years but I've updated a separate system drive to Mojave to move a bit more up to date. On Mojave, Pro Tools opens fine and works but the 192 plays no sound ( no LED activity at all ) and the sound comes from the internal Mac speaker. In the Playback engine and Hardware dialogue boxes I can see the option for Pro Tools aggreagate which I can select ok....but no sound. I know it's not a cable because when I go back to my Yosemite system drive it all works fine again. Could it be a driver issue or firmware? Anyone had anything like this?
