I tried this tutorial :

  * https://jumpjack.wordpress.com/category/infrarossi/

Let's plug the LeD to the HeadPhone plug and see using a DigitalCamera and it's working if sound level are at 100%

Here is the script I used to check :

<code>
    set -x
    freq=19000
    l="1 10 100 1000 1000 10000 19000 100000"
    time=2
    gain=100

    lin="Master Headphone PCM PCM2 "
    amixer -c 0 || return $?

    for freq in $l ; do

    local card=0

    for v in $lin ;  do
        amixer -c $card sset $v  100%
    done

        play -n -c1 synth $time  sine $freq gain $gain
    done
    
</code>

38KHz (2*19 KHz 76/2) is remote control frequencies...
