How to connect an IR receiver to an audio card - LIRC
https://www.lirc.org/ir-audio.html
This is perhaps the simplest and cheapest homebrew IR receiverhardware for PC that can be built ever. It uses just one piece: a IRmodule (any, more details on them can be found on lirc home page) anda (very) optional diode. The schematics. The basic idea is that the output of the IR module (somewhere inthe range from 0 to ~3-4V) can be limited by using the attenuatorbuilt …
LIRC - Serial Port Receivers
https://www.lirc.org/receivers.html
The power for the circuit comes from the RTS line of the serial port. D1 protects the circuit from the negative voltage that is usually on the RTS pin. The LIRC driver will change the serial port settings on initialization so that the circuit will get the

install it as usual. Connect the circuit to the sound-card and set the volume to the maximum level. Start lircd, the -d flag can be used to select the audio device and/or sample-rate, the syntax is api:device[@samplerate[:latency]]or @samplerate[:latency]. Examples: lircd -d ALSA:default lircd -d ALSA:default@48000 lircd -d ALSA:default@48000:0.02
LIRC - CIR

Most receiver chips' latch circuits won't activate the data pin until about a dozen pulses at the carrier frequency are received. When the IR carrier frequency is stopped, the receiver chip's latch circuit will also hold the data pin active for several to a dozen more pulses in length.

WinLIRC Audio Reciever The details for this type of reciever can be found on the LIRC homepage. The idea is, the reciever plugs into the microphone in, or line in on the sound card. The circuit itself is very simple. My homebrew reciever looked like this. The circuit needs a 5 …
[OpenWrt Wiki] LIRC GPIO receiver / blaster
https://openwrt.org/docs/guide-user/hardware/lirc
LIRC GPIO receiver / blaster LIRC is a package that allows you to decode and send infra-red signals of many (but not all) commonly used remote controls. The kernel module used in this howto needs GPIO IRQs, otherwise it won't work. Not all devices have IRQs implemented at the GPIO lines in the kernel.
