The [LINK] cheap chinese HDMI switch we got has an IR remote control that comes with a 3.5mm audio connector to plug in a cape with a TSOP383. | |||
This receiver was plugged into the audio port of a Laptop and the generated audio was captured. | |||
That gave us 5 different Audio files. | |||
The files were post-edited using ?? and now we can simply play them and aattch the audio out from the raspberry pi directly to the HDMI switch IR receiver port with a small piece of voltage converter logic inn between. | |||
