I uninstalled all the sound drivers and loaded up the cd. When I ran it normally it didn't find any hardware to install drivers for. but, when I loaded in in compatibility mode for vista service pack 2, it found 2 pieces of hardware. the LAN driver, and a inf driver?
I tried going into the disk and installing the audio driver manually, installation went all fine and it rebooted. but when it came back on I still had the same problem. the little speaker icon with a red cross over it.
Thanks for your help but do you have any more ideas?
