Switching Audio Between Speakers and Headphones. In the first figure, the plug is not inserted, so the terminal 10 and 11 switches are closed routing the audio to the speaker. In the second figure, the plug is inserted which opens the 10 and 11 contacts thus routing the audio to the headphones. Example of switching audio between speakers and headphones

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 1/2VCC so that the audio inputs to the cmos switch stay within the range of VCC to ground. This assumes that your audio input voltage levels are not more than about 2 volts …

If you really want to switch audio with little more than a simple transistor, consider a circuit like this: simulate this circuit – Schematic created using CircuitLab. Basically what you do is short the input to ground by enabling the transistor. Disadvantage is that the output level will be at least 6dB lower than the input level.
