@Marmite:
I think you will have to use at least some Linux commands to do this.
Can you post some information about your IR remote, and the USB dongle you are using? If someone here has the same one, and has already done it, perhaps you can get more specific help on how to make yours work. And also if you tried it before using it with Rune Audio. (The inexpensive ones sometimes do not work well, so you may want to try it with something else first)
I had a hard time with my Logitech kbd/mousepad combo, it only takes one thing you don't know, or one step you skip, and you can struggle for hours.
Also, I think this thread is mostly about using an IR sensor attached directly to a DAC board, or to the GPIO pins on the Pi (just saying you might get better help if you post a thread with "Installing USB remote" in the title...
)
