https://electronics.stackexchange.com/questions/85721/irda-through-audio-jack
The IR transceiver would be as minimal as possible: just an IR LED and IR receiver soldered to a typical 4-conductor 1/8" audio plug. The basic idea is that the app would read/write to the audio port to control the IR transceiver to talk to another IrDA device. We're assuming the IrDA protocol stack is implemented in the app.

An infrared sound system consists of infrared transmitters, radiators and receivers. The radiator produces invisible, infrared light from an input source (supplied via the transmitter and captured via a microphone or PA source, for example) that wireless, IR receivers first convert into an audio signal that can be listened to using headphones or connected to a hearing aid via neck-loop.
How to connect an IR receiver to an audio card
https://www.lirc.org/ir-audio.html
The basic idea is that the output of the IR module (somewhere in the range from 0 to ~3-4V) can be limited by using the attenuator built into every audio-card (also known as "mixer sliders"). For purists it could be done by connecting a diode so that it shunts any output voltages above ~0.6V (it is shown hashed on the schematics) but this is ...
