In the Control Panel, when I select the icon Multimedia, then Audio I have just greyed out boxes. Also in the Control Panel, although the icon Audio HQ is visible, when selected nothing happens. In the Device Drivers of My Computer I have listed under Other Devices a PCI Multimedia Audio Device with a big yellow question mark through it. In my system I have an ATI Rage Fury graphics card that started acting up and when I tried to re-install its drivers from the CD rom that came with the system all hell broke loose. I could only get 16 colour display, the computer failed to boot up except in safe mode, etc. I have finally got it running more or less normally, except for the lack of any sound whatsoever. Hope you can help?
