Use your fingers or tweezers to pull out the speaker cable from the slide connector socket on the motherboard.
Don't pull on the wires as it may damage the connector or cable.
If that doesn't work, use the point of a spudger to push on alternating sides of the connector to "walk" it out of its socket.
It may take a lot of alternating before the connector comes out.
To reconnect the cable, align the connector and use a spudger or clean fingernail to push it fully into the socket.
Don't push on the cables themselves, or you may damage the connector.
