Make both op-amps in the dual op-amp IC with the same circuit. One of your audio inputs will feed the first op-amp circuit and the other will feed the 2nd op-amp circuit. The ground side of your audio inputs must connect to your circuit ground. Connect each of the op-amp outputs to the input of the CMOS switch. The op-amp circuit will bias up the audio signals to …
