Why alcohol more acidic than aldehyde hydrogen?

Why alcohol more acidic than aldehyde hydrogen?
As aldehyde hydrogen when removed is resonance stabilised aldehyde should be better acid than alcohol.

Don't know the exact answer but my conclusion is : Negative charge is on both C and O and C- is not stable where as in alcohol it only stays on O.
