Hi again,
Just to confirm, the issue is that you are experiencing a lot of latency with the Pro Tools Aux I/O and H9000 usb audio?
How much latency?
Can you do a simple test with just a thru algorithm in an FX Chain and pass audio (a click or short sound) through the H9000? You should be able to measure the amount of latency that way.
Does the amount of latency change when you use a higher sample rate?
Does the amount of latency change when you adjust the Pro Tools hardware latency settings?
I don’t have any experience using the Aux I/O feature in Pro Tools, so I cannot comment on how that may handle latency. You may want to check some Pro Tools forums for further troubleshooting advice.
