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 ...

The Audio signal will be transmitted through an IR LED from the transmitter circuit; the IR signals will be then received by a photodiode which will be placed on the receiver circuit. The audio signal thus received by the photodiode will be very weak and hence it will be amplified by an LM386 amplifier circuit and finally played on a speaker.

This method works with IR carrier frequency of up to 40 kHz. Most remotes are 36 (RC5/6), 38 (NEC and many others) or 40 (Sony) kHz. The illustrations below depict a 40 kHz carrier. That is the maximum possible with 20 kHz bandwidth audio. 40 kHz IR carrier using 20 kHz audio A single cycle of a sine wave. 50 uS period at 20 kHz

Simple IR audio link. Description. Here is a simple IR audio link that can be used to transmit audio signals up to 4 meters. The signal to be transmitted is applied to the base of Q1 via resistor R4.The transistor Q1 drives the IR transmitting diodes D1 and D2.The audio input will be modulated to the IR signals transmitted.

The audio jack IR transmitter sells for just $1.09 on tinydeal, and since it cannot learn the IR code of your remote control, you have to relies on the remote control database in ZaZaRemote app that contains between 58,000 to 160,000 remotes depending where you read. The database is user generated, so it evolves everyday.
