No Unfortunately i found not a soulution. Just selled the yamaha n8 and bought a new mixer/interface.
All so the yamaha support could not help.
Maybe it works with a PCI Card with a from yamaha proposed chipset. It`s the only thing i did not test.
The TI XIO2200 is not working with newer chipsets.

It was really annoying not finding a solution.
