Windows Update zapped my audio a few days ago as well as video. Got the video back by re-installing a former driver. However, have not been able to restore system audio. XP Pro on a homemade system with Creative Audigy 2 zs. Tech support said uninstall all drivers, unplug card, reboot, shut down, re-plug card, restart and install from original CD...didn't work. Then they said do the same thing, but use a drivers install file from their website...didn't work. I can do a test with their software that plays a sound file, but the system has no sound...not even the speaker icon. Any suggestions?
