I'd like to set up a volume control, and there are several videos showing how to do it. They all go to the Special Functions menu, pick a knob or slider and set the function to Volume. I had this working fine on my old radio, but on my new one (I think it's a Mk4, running EdgeTx) the knobs and sliders aren't listed, just the switches.
In all the videos I've seen, switches A to H are followed by S1 and S2 for the knobs and then the sliders.
Any idea what's going on?
