Audio Device in Hardware Posted December 22, 2007 Try this thread:* fixing your sound TUT You should probably go into the Device Manager and make sure there aren't any Yellow Exclamation signs. Sometimes just uninstalling the non-working device from inside of Device Manager, followed by a prompt reboot will cause Windows to re-detect the device. You may or will need either the Windows install CD or the device install CD if doing things this way, however it's a common known fix. Instructions for how to get into the Device Manager. Thanks Andavari for all the advice. Wish I could say it helped but not so. I used the cd for installing & even did a systems restore but still nothing. Guess I will just do without sound for awhile but thanks anyway.
