Tested with 6.7-0235
Opening the Audioplayer reference patch for example doesn’t throw an error but it doesn’t play / position doesn’t update (Oscillator and Noise also don’t give any audible output).
When opening the Audioconfiguration (Alt + C) I am greeted by a black, empty window.
Log says this:
Failed to run handler of VL.Audio Configuration

When setting it to a Asio driver like for example the one from FL Studio it works.
It works in 6.6.
