LV2 UIs can get the sample-rate using the options extension.
Hosts will set the appropriate option lv2param:sampleRate which the UI

I tried that but without success.
I'm using the LVTK library to develop this plugin. My approach is to:
- use the get_supplied_options() method to access the host supplied options
- iterate until I find SampleRate

problem is get_supplied_options() returns 0 options when called from the UI.

Any advice?
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.
