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.

What hardware are you using? And what drivers for the audio devices etc - you can use lspci -v to find out. –  Wilf Dec 6 '13 at 21:59
    
Restarting pulseaudio may work - though using start-pulseaudio-x11 command to start it may work better after killing it. Also, does the sound work after resume if you login as another user? –  Wilf Dec 6 '13 at 22:04
    
@wilf here there result of command pastebin.com/4pxEk2fp, I haven't tried your second option as I'm the only user. –  Megamo Dec 6 '13 at 23:01

I have reported this as a bug in https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1258960 and the problem was fixed in kernel 3.13.
