Hello Mohammed AlSalmany,
I gather your sound was fine before the Mac OS X Update 10.11.3. Thanks for the screenshot.
It sounds like after you have verified there are no audio devices connected to your MacBook Pro then you need to check the line-out port as per this article.
Troubleshooting issues with no audio from built-in speakers on Macs - Apple Support
4. If the Internal Speakers option does not appear in the Output tab and your computer is not a Mac Pro, check that Digital Out is present as in the image below:
- Confirm again that all external audio devices and cables have been removed.
- Check to see if a red light is lit in the line-out port. If so, your Apple computer may need service.
- If you do not see a red light, proceed to step 5.
5. If the issues persist, contact Apple support for further troubleshooting assistance.
Take care.
