No audio input to VST PLUGIN in PRE insert position

I just upgraded to a Steinberg UR824 ( from MOTU 8pre) I Can record audio, but when I add an insert like reverb or compressor as a Pre, I get no audio into plugin. If I put the same insert as a post insert I get audio (when playing back audio).

I can hear and see the audio coming in on the channel - still no audio goes into plugin in the Pre insert position.

Ideas?

I have the same problem! Do you have a fix?
