try changing the delay time!, in my case, (sony audio receiver) working delay time is 40 (not 100),
try other values as 45 (some samsung tvs) or 50...., the time between each command is important
int delaysony = 40;
void loop ()
{
for (int i = 0; i < 3; i++) {
irsend.sendSony(0x540C, 15); // Sony audio encendido
delay(delaysony);
}
}
/code]
Sorry for my english, :D
