Using flirc SENDIR to control amplifier from Windows

[HoochWindgrass]

Hello,

I want to purchase a FLIRC but I want to be sure Ill be able to work out what i need to do before I do.

My situation:

Have PC (Win10)
Stereo Amplifier

My requirement is to be able to turn on/off the amp, and control its volume from Windows command line (my whole goal is to go remote-less)
I know the FLIRC can send IR commands and can learn them too. But the process of doing this via command line with flirc_utils sendir is confusing.

For my amplifier, the RAW IR codes are available in the support manual. But sending that via sendir is where I'm getting stuck.
Volume down for example is:

000 006D 0022 0002 0157 00AC 0015 0041 0015 0041 0015 0016 0015 0016 0015 0016 0015 0016 0015 0016 0015 0041 0015 0041 0015 0016 0015 0016 0015 0016 0015 0041 0015 0016 0015 0016 0015 0016 0015 0016 0015 0041 0015 0041 0015 0016 0015 0041 0015 0016 0015 0016 0015 0016 0015 0041 0015 0016 0015 0016 0015 0041 0015 0016 0015 0041 0015 0041 0015 0041 0015 0689 0157 0056 0015 0E94

But I'm unsure how to 'convert' that info a format that sendir will accept/understand. 

I found these threads below, which are quite similar to what I'm after - but as above, I don't really know how to convert it.
Do I/can I use IrScrutinizer?

 

I asked ChatGPT but it gave lots of incorrect answers. 

 

Thanks!
