For the speaker cable, the connector needs to be lifted straight up to be released. The connector actually fits within a raised socket that surrounds it on three sides (up/camera side, and left and right sides). For this reason, don't try to pry directly from the left, the right, or the camera side, because you will actually be prying the socket rather than the connector. I used a pointed metal tweezer to pry on the bottom right corner immediately next to and just underneath where the wires connect. The socket popped off immediately with little force.
