Unable to kill VSTAudioEngine process

The past couple of weeks I’ve run into an issue with Dorico hanging upon startup at the “Audio engine: Waiting for connection” point. In the Win10 Task Manager, the VSTAudioEngine is running, but probably from a previous session. I can kill the Dorico process, but cannot kill the VSTAudioEngine process (“access denied”). I have to restart the entire computer to get Dorico to run.

It seems that I can start Dorico several times during the day, but by the next day it hangs. This has become a daily problem. Any ideas of what might be causing it, and how to fix it? It all just started happening recently.

That sounds like a misbehaving driver. Have you updated your soundcard driver lately?

Hi @Dennis_Larson , that’s most unusual that you can’t kill a process via TaskManager. Can you please get the free tool Process Explorer from here and try with that one to kill the zombied audio engine? But before killing, please highlight the process and do a right click on it. From the pop-up menu choose Create dump > Create mini dump and follow the on-screen instructions. The resulting dump file please send me, either via this forum or directly to u dot stoermer at steinberg dot de. Thanks

Well, since I posted this I haven’t had a single problem with it. Maybe a Windows update fixed some conflict? If it happens again, I’ll send you a mini dump and a link to this post. Thanks for your help.

Hi @Ulf ,
This has occurred twice in the past week. I’ll send an email to you directly with the minidump and error message. The only solution is to reboot the entire computer (Windows10). Very strange.


Hi Dennis, now this is a very interesting one, one that I have never seen before. The audio engine is stuck in the start-up routine, where still only Microsoft code is called. So Dorico does not even come to the point where Dorico specific code is executed.
Where it stalls is in the initialization of MIDI devices. Do you maybe have an electriclal problem on the wire. It seems almost to me, since you have the issue so irregularly. Please check your cables.
