Cannot connect to the audio engine

I am having an issue with Dorico Pro 5. Most of the time when I open it, I get “Dorico cannot connect to the audio engine. The application will now quit”. When it doesn’t immediately crash, it pauses at “waiting for audio engine” and then I get an odd message about the audio engine in which I attached. I terminate it and then it works for a short time until I get the first message. I attached the photo, the crash report, and the diagnostic log. I hope I get help soon. This all started once I had Finale open with Dorico.

Hi @hauck.josh ,

first of all, welcome to the forum, but please do not post your problem in several threads, please stick to this one here.
Also thanks for the diagnostics data and ips files. The diagnostics tell me that the audio engine is mostly running fine, but occasionally crashes in the code that checks for licences. The callstack pattern is new to me, so it has nothing to do with all the other frequent support requests about not being able to connect to the audio engine.
Monday I will raise this issue with the appropriate engineers. Until then I can only ask for your patience. Thanks

I am running the 60 day trial and I am about to purchase the crossgrade from Finale. I restarted my MacBook and fully updated it to MacOS 14.6. Now it is working fine, but the download system is crashing. I get this image that I attached.

Maybe when I purchase it, I should uninstall everything from scratch? If so, how do I do that?

Also, sorry about posting the problem in multiple threads. You are correct, I should not have done that.

No worries.

Can you download the Download Assistant from our website from here?

But actually, the installation can stay the same, only the license needs to change.

So the question is, do I have a faulty license? If so, how do I replace it?

So Dorico now runs fine with you, right? If that is the case, we’re basically done. That with the Download Assistant is just a hick-up. I don’t know exactly if that connection problem will go away by itself or if an update is necessary, but that is a completely different issue to your initial problem of not being able to connect to the audio engine.
And license-wise it is also fine, You can now use the trial license, and then later - if you like - buy the full license. The full license you register with the Steinberg Activation Manager and you simply continue working with Dorico just like same before. No need to reinstall Dorico or any of its components.

Nope. The issue came back after I deleted an .xml file into the trash. At times, Dorico opens fine, then at times, I get the same message saying: “Dorico cannot connect to the audio engine. The application will now quit”. When I save a file, a copy automatically moves into the trash after I close it. I have auto backup unselected. What is going on?

Here is the Diagnostics file.

That with the files in the trash is normal behaviour. Dorico puts every file it temporarily creates into the trash rather than completely killing it, so users still have the chance to retrieve it from there.
That with the cannot connect is most likely a bug. When closing and reopening Dorico checks too early for the new audio engine process.
May I ask you to try that if you shutdown Dorico, wait a couple of seconds before relaunching. Thank you
