I got this Satellite Pro 4600 laptop and untill recently I had a perfect sound. I don't know what happened but it isn't working anymore. The problem is that it doesn't detect any Audio devices. In the Sounds and Audio Devices Properties --> Hardware. I go to my Intel(r) 82801BA/BAM AC'97 Audio Controller and choose the Properties option. Than there will pop-up a new screen with several Multimedia devices I got and when I check their properties they all have this status: Status: Driver is enabled but has not been started. Anyone knows what to do with this?
