Hi there, this is might be a really easy solution that I am just overlooking because I am newbie to such a sophisticated piece of gear.  I got the RayDat hooked up in my XP 64 computer, it seems to be powering up fine (ADAT is lighting up), and audio seems to be going to it (the meters in the RME mixer are moving), but I cannot get sound out of it.  Just some other notes:

-  Windows XP64 OS.
-  Didn't install drivers from CD when I got it two days ago, I went directly to the RME website and downloaded the newest drivers and did the flash update. 
-  Using East West Quantum Leap Brass XP Platinum standalone application, I can see audio is going to the card because the RME mixer meters are moving up to about -18 dBfs.
-  I made sure all of the faders were up in the mixer and that audio us being routed to ADAT 1 + 2.
-  I have the ADAT1 out (ch. 1 - 8) hooked-up to a headphone DA converter.
-  I have tried all of this in Reaper too, and nothing is working.
-  I have tried the other 4 ADAT outs and nothing

I am apparently overlooking something.  I've made sure nothing is muted, nothing is turned down, all audio is going to ADAT 1/2, etc.  Even checked to make sure my headphones weren't fried and they are fine too.

What could I be doing wrong?

Thanks,

Uro
