Thank You So Much. I will try all the following, and i will come back to you with the results. Have a nice day!Boot up the MBP.
Turn it around.
Look into the headphone jack.
Do you see a "red light" on in there?
If you DO see it, that means the jack is "set" to optical-out, and is providing a digital signal to the port, even though there's no headphones plugged into it.
So, the speakers won't work, because the Mac "senses" there's a connection in the headphone port (even though there isn't), and switches the speakers OFF.
If the port gets "stuck" in the "digital-optical out" mode, now ordinary headphones won't work, and the speakers won't work, either.
Here's a link to an article that "unsticks" the port the old-fashioned way -- by inserting/removing a headphone plug several times:
My MacBook seems to be stuck in "Borg emulation mode" (red light) with no access to the built-in speakers
So it seems I've done something to mightily mess up my new MacBook Pro. The other night while in my hotel room at AstriCon, I was using my headset for some Skype calls and then had it in when I...www.disruptivetelephony.com
But if that doesn't work for you...
Some years' back a MacRumors user figured out how to disable the optical-out signal using software.

My 2009 MacBook’s speaker doesn't work (most times). The digital audio out port gets stuck (a red glow appears from within the socket). It is an old MacBook with separate headset & mic ports....apple.stackexchange.com

Hi, I followed the steps but unfortunately, nothing worked. After installing Kext Utility and Voodoo HDA still have same problem only some digital out's were added to the MIDI Setup App. But Thanks!Boot up the MBP.

Ok, I'll try that. I used multiple types of headphone plugs. None of them worked. Thanks.
Thanks a definite maybe.
Hello Again, Unfortunately installing El Capitan didn't work. but I tried the pin trick where I opened my MacBook then i stuck a metal stick between these pins and the built-in speakers came back but after I remove it the same problem appear again. I don't know what to do at this point.
If the resets do not work then I would say it looks like a faulty socket most likely. Maybe you could live with a Mac-compatible USB sound dongle? Or maybe use bluetooth for sound?
