Open the RayDAT's Settings dialog and set the number of WDM devices to 0. If that works try again with a setting of 2 and check the default playback device in the Windows Sound panel.

Best practise is to disable onboard sound.

Is there a possibility to always use the RayDAT like I did on my gaming PC ?
I used the UFX for AD/DA (monitors, phones, etc).
What do you have connected behind your RayDAT ?

What mainboard do you use, what PCIe slots are used by what card ?
Can you check whether other PCIe slots eventually result in more stability ?

Maybe also worth to try another nVidia driver, one time I had issues with the driver.
No crash but I had a completely laggy slowed down graphics.

My idea when buying the RayDAT was, to use my I88x for getting the analog Instruments into the system, then send them to the RayDAT and then get the data turned back to analog audio by the I88x again.
That way I would have an output that my amp can handle.

Turns out, I couldn't get the AD/DA part of the I88x to run as a standalone device and I can't use the MLan software on a win7 PC.

So the current state I'm in is: I have a RayDAT that I can't use yet, because of missing additional hardware.

Regarding that required hardware I'd have the next question - again: If you think I should up a seperate thread for it, please tell me and I will.

- Do I understand it correctly, that the RayDAT has a wordclock in it?
- So could I just get that 1 wordclock in and 2 wordclock out addon card and just connect to external devices to the RayDAT without the need for an external Wordclock?

And the next question goes back to one of ramses's questions:
Currently I have use the only pci-e slot left free on my motherboard (GTX 1080 blocks all the others).
The slot it is in now in is extremely close to the gpu so the airflow to that card is halfway covered by the RayDAT.
There is still another option with the pci-e 8x port that would usually be there for a second graphic card.

- Would it be ok to use that port for the RayDAT?

According to Heise
https://www.heise.de/preisvergleich/gig … 94987.html
Erweiterungsslots: 2x PCIe 3.0 x16 (1x x16, 1x x8), 3x PCIe 2.0 x1, 2x PCI

So this means the GPU should stay at x16 and the 2nd GPU socket, which you can use for the RayDAT would get at max 8 PCIe lanes, but the card in fact will use only one.

With programs like CPU-Z or maybe GPU-Z you can validate how many PCIe lanes are in use for the GPU.

no wait. you probably won,t need wordclock. the digital connection, adat or spdif will carry the clock. WC will make it more complicated then needed and not better.

For cd record in 44k. Always 24 bit if you processing later. Don't forget to dither when mastering at the end

I hope it is as simple as setting up the i88 to output it's analogue ins to adat under XP and the booting in win7. If you connect the adat out of the i88 to the raydat in and keep the clocking as it is now, you will see if the inputs are working in totalmix (top row). Might even work without setting it up in xp so just try that first. Another idea, you could maybe use an old computer or laptop connected via mlan permanently to have access to the i88 setting. I have a similar setup. I use a FW1804 as mic preamps, but it connected to another computer then my daw and it connects to my DAW pc via adat. Only the 1804 is firewire not Mlan.
