This problem is already known but the given solution didn't work for me. When I suspend Ubuntu, in resume I don't have sound. The solution that work for is to force shut down (by pressing the power on button for 5 seconds). Restarting or shutting down the computer normally doesn't help. I've got similar problem when I restart from Linux to Windows, I don't have mouse. The solution to get back the mouse is also to force shut down. I thought that problem is Windows 8 but now I'm sure that is Ubuntu
Can someone could help or explain me the difference between force shut down and normal shut down. Thanks in advance.
