Windows 7: Lenovo, windows 7 64, no sound. First suggestion. Go to the Device Manager, RIGHT click on the RealTek entry and then LEFT click 'Uninstall'. DO NOT check the box to also uninstall the drivers. Restart the PC and when Windows starts it will detect and reinstall the sound. If there were any Windows corruptions, this will fix it.
