Thanks for your reply - it sounded like the answer, so I downloaded the
latest SigmaTel driver from Intel, but it didn't work. When I try to check
SigmaTel through the Control Panel, it says the driver is "inaccessable. Make
sure it is installed and enabled." Checking for the line-in connection, it
says Digital Input Device (SPDIF): High Definition Audio Device is working
but not plugged in (it is, of course, & was working before Vista.) It also
says it's a Microsoft driver, not Intel. Did it replace & disable the Intel
driver? My Intel board is a D946GZIS.
