Hi @ah309 ,
there are probably two issues here. First, you have the new HALion Sonic 7 with the new MediaBay4All which makes the audio engine hanging and waiting for a response from the MediaBayServer. In the diagnostics are two dump files that clearly show that. Have a look at this thread for a temporary workaround. Please try that and see if you still get this hanging of the audio engine.
In regards to no audio coming out, could you pleases try to export a project to Wave format (File > Export > Audio) and see how that goes?
And by the way, you have routed Dorico to stream to Voicemeeter, but where does Voicemeeter send its output to?
