Hi - it appears that the multimedia audio controller problem that I had has now morphed into a REALTEK AC'97 Audio problem. I loaded a driver for the mother board to fix the MAC problem after helpful folks assisted me in getting the specs on the motherboard (ECS PS45A/DX+1.0 if it makes a difference... ) and now the device manager says the REALTEK AC'97 Audio "cannot start - Code 10". I downloaded the latest driver for this device ( and computer still has no sound, and Premier Elements says it cannot start because it cannot find audio drivers. Any more ideas here?
