I recently had to do an XP repair because of the numerous problems a virus caused. Since then I am having audio problems with my LG GH22LP20 DVD Writer. I get sound, but when music plays it is sort of garbled. It is just the LG GH22LP20 DVD Writer, I am not having this problem with my other DVD burner. I have tried uninstalling it in the device manager and reinstaling it with the installination software, and updating the firmware. Can you please give me some idea of something else to try?
