Speak to your host developer.

In my host LV2 UI code I have this:
https://github.com/falkTX/Carla/blob/master/source/bridges/CarlaBridgeUI-LV2.cpp#L124

The sample-rate is passed via options feature to the UI, among other things.


btw, option extension uses lv2:sampleRate and not lv2param:sampleRate, 
my mistake.
