@santagary first try this:
Check in System Preferences: Sound:
- Output that sound output is set to “Internal Speakers”. and balance is set to center.
- Use the F12 volume key to set the sound to maximum.
- Reset PRAM.
Unplug headphone/external speakers and verify if you now get audio through internal speakers. Cycle through this plug /unplug operation several times in rapid succession and verify if audio gets back each time to the Internal speakers.This might loosen a stuck headphone jack. Of course this will only be diagnostic if you have audio on your headphone/ external speakers.

@santagary do you have sound when you plug in a pair of headphones? It is possible that this is caused by a bad headphone jack. What have you checked?
