Sound does not go into the buil-in speakers

[andrei186]

MacBook PRO - sound does not go into the buil-in speakers, yet still OK with the headphone.
Thy system sounds (like that when Windows loads) still work.
Was told that the block which switched between the speakers and the headphones is out of order, but here in Russia they do not have it.

Is the problem with that block? Is it repairable or only replaceable? Is it awailable somewhere and how is it called

This is the US site, try the Russian site.

I only say this because I do not understand what your saying. I do not know what a "block" is.

Or you could try Apple support.

Sorry for twisting your brains, GeekApproved, by "block" I meant bloc (sorry for misspelling) which according to Google means unit or assembly - could not u figure this out from the context?
FYI, I applied to Apple support and they refered me to their Russian dealers who in turn referred me very far away if u see what I mean
