One speaker still does not play

Disconnect the wires from both the speaker and the mixer. Disconnect the other wire from its speaker and connect that end of the wire to the speaker that doesn't play. If the speaker still doesn't play, the problem is in the speaker. If the speaker now plays, continue checking for the source of the problem. Disconnect the same wire from the mixer. Connect it to another output. If the speaker plays, the problem is the original wire that was connected to that speaker.
