I have a Dimension 4600 with what is listed as a P1554 Sound Blaster Audigy 2 sound card. After a recent update from the Windows Update site (not sure exactly what was downloaded-should have paid more attention), I no longer have any sound. Everything looks like it's installed propertly when I check my hardware settings and drivers. I went to Creative website but wasn't sure exactly which card to select under the download section (none matched exactly-? since mine is an OEM version). Anyway, my thought was to uninstall the driver on mine and then reinstall it. Does that sound reasonable? Is there any type of diagnostic I can run to figure out what's going on? The automatic update program on the Creative site won't run because it says something is "corrupted." The only program I see under my Add/remove software that I question is "voxware audio decoder 1.6." If anyone can give me some direction on solving this, I'd appreciate the help.
