No Internal Speakers in sound MacBook Pro 15" Early 2011 - speakers won't work, only in win 7

yesterday I've disconnected the headphones while also using the secondary monitor,

and the headphone jack turned red and the internal audio stopped working, the funny thing is that the headphone jack actually works fine, its just shining red and the speakers stopped working BUT ONLY IN Mac OS, WORKS IN WINDOWS 7 THROUGH BOOTCAMP, I just don't know what to do, I've dusted it out and still the same problem, now I have to use the trash speakers in my old monitor, ONLY SHOWS DIGITAL OUT WITH NO MONITOR PLUGGED IN

NO, I CANT AFFORD A NEWER MAC

MacBook Pro 15″, macOS 10.13

Go step by step and test.

Insert and remove the headphone plug into the audio jack 4 to 5 times.

Sound output is stuck in the digital mode.
