Recorded OK. And you know, this same receiver emits codes to TV if pluged to audio out. I think this is better to use, because it allows us to record the IR signals too (works as receiver-emiter), compared to emiter only sugested by pdca.
Indeed this wont work from smartphone anyway.
EDIT: if anyone wanna to play, here are codes for info menu mute power, dont know what is sufficient count of signal, i replicated it 4 times. POWER_from_REMOTE_inv.7z
p.s. does it make sense to join all to one file, eg, Enter_SM.wav?

Another keys/combination requests?
