Hello, I've searched this forum, and others, and haven't found a solution for this problem. I have no sound for anything. I have a Realtek AC'97 audio, running Windows Service Pack 3. My motherboard is an intel corporation one. My laptop is a sony vaio pcg-z1wamp. In the Device Manager it shows the following: "Device cannot start (code 10)". I've tried installing several new drivers; I've uninstalled and installed the device; I've tried updates and some of the solutions suggested on this forum. Nothing has worked. Hardware issue & problem persists. Any help would be greatly appreciated.
