Thanks for your help. I found an AC97 Win 7/vista 64 bit driver *from"
named "Vista_Win7_Win8_R270(1)" from the realtek driver site. Downloaded it w/o trouble, and ran it (exe file) rebooted and the little speaker went from a red X to a normal icon. All seemed fine, but no sound. Looked at the drivers..checked out okay. Checked all the sound setting, volumes mixer settings, etc. speaker plugged in. No sound from speaker or headphones, grrrr!
Device drive settings in Control Panel seem okay..states drivers working.
here is a picture of the driver in device mgrhttps://docs.google.com/file/d/0B86KNn568tenZWFZT0ZVOG9Md0k/edit
Any other ideas, ?reload river after deleting it? Am I missing a setting?
