Creative didn't exactly follow PCI specs when it designed the Live! cards. While it typically shows up in Via-chipset based systems, they are known to have issues, like what you've described. The Live! series required 2 IRQs, one of which was for MS-DOS usage. That's been the bane of BSLive! users everywhere when it came to using it under Win2k. Sometimes motherboards can be picky about certain things. I'm not all that familiar with Soltek, so I cant' say if they've got any issues that span their motherboards. More than likely, it's the Live! showing off Creative's screw ups.
