I find the minimal value (10) for volume step quite high. Is there any possibility to offer more values (5 and 2 for instance) of exponantiel like update behavior (if the key remains pressed for some time for instance, increasing/decreasing would be using a large step, when pressed only once, the step would be minimal) ?
This is something best asked for on Kodi forums.
But Volume Control Steps is the number of steps to go from minimum volume to maximum, so a setting of 2 would make no sense as that would just give you no volume, half volume and full volume.
If you want smoother, ie more granular, control then you need to set the steps higher, the value goes to 90 I think.
Yes, silly of me, you’right. I believed it was the step relative size
