No sound from gigastudio...sometimes

[Phyl]

I had a computer built for gigastudio:

Athlon XP (1.8GHz)
512 MB RAM
Drive A - 20MB (OS and gigastudio)
Drive B - 40 MB (giga library)
PCI-822 card (cam bundled with giga)
Windows XP

I installed gigastudio and giga piano, everything seemed to go well. I also installed the PCI-822 drivers. I connected the PCI-822 SPDIF output to the SPDIF in on my aardvark Q10 and connected the aardvark to my monitors. My midi keyboard is connected to the MIDI #1 channel of the PCI-822.

When I start gigastudio and load the piano, I can see the MIDI activity indicator in giga light up when ever I play my midi keyboard, but no sound comes out of my monitors. What is stranger is that if I load a CD in my computer it plays just fine through my monitors. Somehow the CD audio is getting to the PCI-822 and out the SPDIF interface to my monitors but giga doesn't seem to be sending anything to the SPDIF port.

I've looked at the system settings within giga and can't find anything that looks wrong....WTF???

Any ideas???

Thanks
