@loekf - there's the issue. WASAPI is just the render method - it is effectively passing thru right to the audio driver.
When XBMC is set to decode DTS (DTS 5.1 --> PCM 5.1) that's fine, but that's where it ends. SPDIF cannot send 5.1. If your Creative has 5.1 DACs and you are then using 3 prs of analog cables from the sound card to the receiver, that's fine, but not SPDIF.
To make matters worse, your card is reporting that it's only 2ch PCM, so even the second step there won't work, the PCM 5.1 --> Creative.
Check your Creative setup software and make sure it can accept 5.1pcm because it's not reporting that to Windows. Won't be the first issue I've seen with Creative's drivers.
I'm off now to go see family for the weekend, back on Monday if I don't check in somewhere in between, but keep me posted on what you find out with the Creative setup.
