Hmmm, here's my 2 cents:
Until very recently I was totally unaware of wasapi. In fact I'm more of a Linux, OS X & Opensolaris man. (thinks storage & ZFS) I have quite some hardware around the house, and I started out with an Acer Revo R3600 (ION based) as this box can be really very green (powerwise Watts), and as it had Vista on it. As I read that Win 7 stood out for wasapi, I quickly installed Win 7.
For all I tried I could not get wasapi to play game. I finally found that the hardware was the culprit. (chipset limit)
On a secondary line, I did some testing with my
Onkyo TX-NR906. This one is 24 bit, 192 kHz capable.
It is UPnP and DLNA capable. Allthough nowhere to be found in the specs, it can handle flac up to 192 kHz. But I find that when I directly connect a USB hd containing highres flac, it will only play up to 96 kHz...
Using it's network connection, connecting to MC15, it plays 192 kHz fine...
Another experience: I own an elderly Sony AV receiver (STR DE675)
Searched through the manual, yep, it can handle sample rates up to 96 kHz. Off we go..
But alas, it only handles 96 kHz on its DVD/LD input..
So what's in it for you?I'd say first study your manuals and try to find out what the hardware is capable of. For motherboards it's often hard to find, but usually you can find at least an indication. Also, and I'd say even quite often, hardware is more capable than its specs read.
How I do it?Download PDF manuals and use the search function, keep your searches as short as possible, search for kHz, or sampl*
My Gigabyte mobo is specified up to 96 kHZ, but handles 192 kHz on it's optical out.
Back to your Julia situation:I'd suggest you head over to Vincent Kars tremendously interesting site at
http://www.thewelltemperedcomputer.com/SW/VistaTweak.htmRead up on looking at, and testing your configuration. Most of all: take your time.
Start testing from within Windows, if you have win 7 you can see what your hardware is capable of.
Mind that it's not always very clear what you're looking at. In the Juli@ case most of the time you can recognize the naming. But otherwise you my find things like 3-speakers, 3-spdif, 3-HDMI and such.
As a general experience, win 7 will show what you have on board. It may differ consideraby from PC to PC.
If you still have questions, I can post a couple of screenshots of my config.

Then perhaps a last piec of advise:You're obviously familiar with MC15's options screen.
I find it rather confusing in that MC15's option screen will always look the same, but it may be treating different hardware depending on what you have in your machine, and where you are in MC.
I find it most direct to look in the tree, under playing now, I have set each of my audio outputs as a zone.
Choose your zone that is linked to or contains the Juli@ card, rightclick context sensitive menu, playback options;
you'll end with the familiar options screen, but you'll be sure it's handling your precious Juli@ card...
All the best,
Erwin
