It is picturised in many movies snakes ( especially cobra) drinking milkand turning hood in reponse to a typical musical tone. Can cobras realy drink milk. They have split tongues and can cobras respnod to sound waves?

Well, I think you're asking a different question then what you want. You ask can a snake drink milk. Well, I'm sure snakes are physically able to. After all, they most certainly drink water (though they absorb it through their scales also). So, if they can drink water, why not milk?

 

However, would they drink milk? AS to that, I'm not sure.

Snakes can't hear, they do sense vibrations when they move along the ground.

It should be noted that hearing IS the sensing of vibrations. What makes it "hearing" is not that it is detecting those vibrations (that is, sound), but that a particular organ is taking it in and the brain is interpreting it in a particular way. A snake can be aware of the air vibrations that we would call sound, but it experiences it differently than we do.
