Will the SOtM USB card work with Windows Server?

Try asking this at computeraudiophile.com or at the PCaudio forum in the JPlay website. I know people there use this combo.

FWIW, I use a PPA v2 USB card with WS2012 without issues. I built my server 15 months ago and don't even remember if I needed special drivers.

BTW, I assume you have asked the manufacturer, right?

Where do I get the driver for WS?

it is. backwards as well.

Anyone? Just needed to find out if this board is compatible with the WS operating system.

It is just a friend that knows computers but not much about audio.

It should work. Doesn't the person who's building your PC know? If it was my PC that they were building, I would expect them to already know this type of thing.
