Just to let you all know that I have finally bitten the bullet and sold my MOTU 828 MKII. As far as I am concerned, MOTU's development and testing for the Windows platform is woefully sub-standard. Couple this with the terrible product support infrastructure and processes and you've got a lot of ann...

Try switching off your WiFi controller.

You definitely completely uninstalled the newer drivers before applying the older ones?

So I finished basic testing of the older version of the MOTU drivers with a ACPI HAL (the default Windows XP install) and am pleased to report that it was successful. It is as stable as my previous non-ACPI build and I still don't have the annoying screeches and noises. I am going to stress test it ...

Hey there, d-brane,

Before you do this, wait until tomorrow - I will have the results of the older MOTU drivers test that I mentioned earlier...

This method MIGHT make it so you can just downgrade the drivers. I need to finish my install and testing this evening.

UPDATE:

After some assistance from "disco", I am currently trying a new PC build with an older version of the MOTU drivers.

I'll let you all know how I get on in due course

I do agree that the core problem lies in the fact that the flaw is within the MOTU drivers as plenty of other audio interfaces work seamlessly with Windows. However, with at least the last two releases of the MOTU Windows drivers not fixing the problem, and no new drivers in sight, how else do you p...

Hey there, d-brane, To tell if the problems you're experiencing are similar to those that I experienced, you should install ProcessExplorer on your machine to find out what's happening to your CPU when the problem occurs. You'll know it's the same problem as you'll see a rise in the percentage of CP...

It wasn't a clocking issue...

The fix was partly the hard-drive, and partly the Windows installation re. IRQ and sharing. If you have this problem on a laptop then you would have to replace the drive and reinstall Windows. As far as the IRQ sharing goes, you would have to reinstall Windows and selecting a different Hardware Abst...

Of course, if you bother to read the whole thread, you would see that the problem was in fact caused by using an ACPI HAL and a faulty hard drive. The solution was to install a non-ACPI HAL and to replace the hard-drive. That article points out that without using diagnostic tools, you cannot begin t...

This is also a very good read...

No problem at all. I know how frustrating it can be...

Read all of it and you'll see that the problem is not with the Video Card itself, but with your Windows installation...

Look for the bits about Hardware Abstraction Layers and IRQs - ignore the early GeForce stuff in the thread...

Sounds like you've got a conflict between your Video card and your USB root hub
