Help!!!! No sound in my Windows 7

[Lord of the Kings]

When i just watched a Assassin's Creed 3 Tyranny of King Washington,i discovered there was no sound.
I checked but it wasn't muted so try a lot of solutions but didn't work.
I believe that my AMD HDMI was unplugged but i am using latop,there was no such thing as an AMD HDMI cable.
I am hopeless to post this thread!!I need your help!
I will rep anyone who found the solution.

Click on the Speaker Icon on the lower right
Click on Mixer
see if it's muted...
Unmute

If it's not that maybe go to control panel and then sounds? To see if everything is ok.

Did you try turning it off then turning it back on

Could try this.

Open your mixer, click on system sounds, go to playback tab, and make sure that your default device is correct.

My Speakers was default device and AMD HDMI was unplugged(i don't think it was the problem).
When i test the speakers in my latop,ERROR:Failed to play test tone!

check your audio drivers are working properly you can do this by going to start>control panel>system and security>device manager

If there's a problem with the audio like the pic above, try disabling it and re-enable it this sometimes helps or try uninstalling it and installing new drivers, hope this helps
