"learned through media" looks like  you did. Charvaka was a fake metaphysics created by colonialists to promote hedonism, greed and gluttony so that then Indians focused more on Kam rather than Karma. Since it is mentioned in some books do not mean it is part of the tradition.

In other words, you have to logically and experientially validate them by having correct understanding of Vedic metaphysics. There are just 3 main metaphysics. Sankhya = Advaitha + Dvaitha. They don't contradict each other. Advaitha and Dvaitha are INCOMPLETE without each other.
