"The movie you gave us DOESN'T have sound" is correct.
The choice between DOESN'T and DON'T depends on whether the subject is single or plural.
Single subject: use DOES, DOES NOT, or DOESN'T. "My cellphone DOES work", "The answer DOES NOT matter", "The movie DOESN'T have sound".
Plural subject uses DO, DO NOT, or DON'T. "We DO like you", "Those books DO NOT belong there"
