No, you won't.  All sound encryption schemes use a bit of random to make
the resulting ciphertext different.  In the easiest case this is called
a salt and used to stop dictionary attacks.  For example, such a salt
has been used for 25 years or so on all Unix systems to protect the
login password.

No.  Different ciphertexts may yield the same plaintext.
