You guys are great. Many thanks for all the tips and suggestions. In a nutshell: 1. Be sure all latest drivers and updates are installed. A variation on this was to reinstall the original ac97 driver that shipped with the motherboard. 2. Get into Windows and/or bios to resolve address or resource conflict. 3. Put the pci card into a different slot so Windows will see it differently. 4. Consider adding a usb audio device. Lots to play around with next week. Tnx again. 73,Ste ve KW3A kw3a at snip.net http://www.writelog.com/ >> _______________________________________________ > WriteLog mailing list > WriteLog at contesting.com > http://lists.contesting.com/mailman/listinfo/writelog > WriteLog on the web: http://www.writelog.com/ >>>
