I have a sony crx215E5. My computer will play audio cds. but i insert a blank cd and it doesn't recognize anything is in there. I've tried updating the drivers. I've tried uninstalling and reinstalling. I've tried setting all programs to default. When i search for updated drivers it says that i have the most current drivers. The device manager says it's working properly. I've tried different types of cds. I've tried using a program to clean up the registry. Does anyone have any information?
