The 26.0.02 version of OBS studio available at the PPA below includes a VST 2.x Plug-in audio filter wrapper.

Has anyone figured out how to access any of the VST plugins in OBS? I can add the "VST 2.x Plug-in" to the filters from the dialog but then the drop-down "{Please select a plug-in}" menu is blank. I have plenty of VST plug-ins installed, I can see them in carla. I also installed the reaper vst plugins in wine and the 64-bit reaper vst plugins with wine64. Please suggest on how to get this working with OBS or the best way to verify at least some my VST plug-ins are working (typically I prefer the free native lv2 plug-ins).
