Can I get audio input through the GPIO - Raspberry Pi ...
https://raspberrypi.stackexchange.com/questions/4341/can-i-get-audio-input-through-the-gpio
The Pi has a standard 3.5mm audio jack, but this cannot be used for audio input. However, we've got a load of GPIO pins on various interfaces. Would it be possible to recieve analog audio into the Pi via the GPIO? Elinux tells me: It is also possible to reconfigure GPIO connector pins P1-12 and 13 (chipset GPIO 18 and 21) to provide an I2S (a hardware modification may be required ) …
raspbian - How to output audio signals through GPIO ...
https://raspberrypi.stackexchange.com/questions/49600/how-to-output-audio-signals-through-gpio
On recent Pis the audio jack output is provided by PWM channels 0 and 1. PWM channel 0 is fed to GPIO40 which is connected to the (stereo) right channel, and PWM channel 1 is fed to GPIO45 which is connected to the (stereo) left channel. These PWM channels may additionally be fed to user accessible GPIO.

Audio Switching via GPIO. Main audio, normally flows to the software, upon a trigger event, I switch to ALTERNATE AUDIO to be sent to that piece of software, and then when the trigger is released, switch back to normal audio. I've looked at a ton of the various relay boards out there,Pecan etc., but they just are really not a fit for my project ...

GPIO #18 is also known as PWM0 and in the original Pi was coupled with a very basic RC filter to create the audio output: If you don't mind getting a few 150 and 270 ohm resistors, and two each of about 33nF (also known as 0.033uF) and 10uF capacitors, you can basically recreate those two filters. Now all you need is access to PWM0_OUT and PWM1_OUT, …
