I have a continuous tone output with aplay, can anyone guide me as to how I can route the audio input jack to the output via the terminal?
Are there any beginner-friendly tutorials out there as I am abit lost atm!

HiFiBerry team Do you want to mix an input or aplay playback? In this case, you have to use some kind of mixer, e.g. the "dmix" module of ALSA:

Note that this isn't a trivial configuration. You can have a look here:

Note that this is an old guide, you might need to adapt it.
In general, this isn't all "beginners" stuff!
