I have an amplifier from Audio-gd – Precision 1 ([Link: tinyurl.com])

I want to use my Samsung Galaxy S4 to control the volume, so I asked the manufacturer for the IR-codes. This is what he returned:

The chip is NEC.
First Code :0x80

User codes:
case 0x16: select=1;
case 0x17: select=2;
case 0x11: select=3;
//case 0x4F: select=4;
//case 0x12: select=5;
case 0x05: volume++;
case 0x19: volume--;
case 0x4c: out++;
case 0x18: gain++;

I then went to this page to convert the NEC-code - [Link: irdb.tk]

I figured I had to convert the NEC HEX to decimal and for the volume++ i entered: NEC1 0 128 5

This was the output:
0000 006C 0022 0002 015B 00AD 0016 0016 0016 0016 0016 0016 0016 0016 0016 0016 0016 0016 0016 0016 0016 0016 0016 0016 0016 0016 0016 0016 0016 0016 0016 0041 0016 0016 0016 0041 0016 0016 0016 0041 0016 0016 0016 0041 0016 0016 0016 0016 0016 0016 0016 0016 0016 0016 0016 0016 0016 0041 0016 0016 0016 0041 0016 0041 0016 0041 0016 0041 0016 0041 0016 06FB 015B 0057 0016 0E6C

But it doesn’t work. I do not have the knowledge in this field to understand if I did something wrong. Can somebody help me?
