Thanks again for your kind reply!

Are you seeing something specific that leads you to believe ExecuteAddon isn't working?

Yes: Entering "http://<MyKodi>/jsonrpc?request={%22jsonrpc%22:%20%222.0%22,%20%22id%22:%201,%20%22method%22:%20%22JSONRPC.Permission%22}" gives me


id 1
jsonrpc "2.0"
result
ControlGUI false
ControlNotify false
ControlPVR false
ControlPlayback false
ControlPower false
ControlSystem false
ExecuteAddon false
ManageAddon false
Navigate false
ReadData true
RemoveData false
UpdateData false
WriteFile false

I should mention that these limitations seem to be only for http calls. Python calls should work, but writing python code is far beyond my abilities.

But I've finally found another solution:

In the custom commands menu, Yatse (free Version!) will let you import some commands from Kodi, among which is a numeric keypad. So you can use this keypad and map audio profiles to numeric keys.
