...oh, nevermind. After a day and a half of struggling with this, I finally found:

Edit->Preferences->Devices/Driver Settings

Among other things, running the Wave Profiler and mucking with the checkboxes next to the available outputs seems to have done the magic trick.

¯\_(ツ)_/¯

I'm having the exact same issue, and I'm completely at a loss for what's wrong.

As you can see... I'm generating signal from the VST's virtual keyboard. It's showing that things are working. We're seeing life on all the meters... but no sound is coming out.
