Funny I was just trying to do the same thing when I read your post
I’am very frustrated with running the H900 alongside my Aurora Lynx(n)
no luck using it on port 1.
I did manage to make it work one day on port 2 with the Lynx on port
Can’t make it work again
all the green light are on but I still get some clicks
Hope you have better luck than me, let me know if you found a way
PS:I also tried to clock all with a GenX96 with no success
