Dorico won't select audio device...

Understood Daniel, no doubt you have your hands full. I’m looking foreword to using Dorico, I admire the work ethic of you and your team. You have undertaken a daunting task, with demanding masters.


Hi JM,

indeed, weird behaviour that we can’t explain by now.

Additionally, could you please zip up the contents of following directory:

There are one or more log files of the audio engine in there. These are more useful for us to look at.


Ulf, where might I find said directory?


If you open the Terminal app and type…

open $TMPDIR/VSTAudioEngine

…it should open a finder window at the right place.


Weird, should work straight away. But in the error message is one slash too much.

So in the Terminal, could you please manually change directory to that place but leave out one of the slashes?
In other words

cd /var/folders//T

and then do

open VSTAudioEngine

Uff, I’m not exactly sure of what you’re asking me to change…


Ulf, I’m sorry…

The extra slash shouldn’t make a difference.

Could you try just:

open $TMPDIR

Is there a folder called VSTAudioEngine in there?

Ok, that opened a folder, what am I looking for in said folder?

Another folder called “VSTAudioEngine”

As you can see, there is no such folder…

Then it looks like that the Audio Engine doesn’t have the access right to write to that folder.
How can that happen? Well, from difficult to impossible to diagnose from remote…

What would you suggest? It seems that Dorico is in beta stage at best.

I’m sorry that you’re experiencing these issues. We’ve been in beta for a while and haven’t experienced this issue so far in over 200+ installations.

Is your user account on your Mac set to Administrator level?

Have a look… (18.3 KB)

I was looking at an HD in Finder, and it indicated that the administrator had read/write privileges. When Get Info about Dorico was selected, administrator was read only. I have two other Steinberg products, and they were both read/write for the administrator by default.


When I choose the audio device it still won’t stick, but these temp files appear in folder T.

Aha - that’s good, they’re there. I’ll let Ulf download them when he’s back in the office and follow up.

Okay, from the log files I can see that the engine is always trying to load another driver, but then immediately switches back to the built-in audio driver. We haven’t seen this before.

Further, I don’t know any of the other drivers that you have installed. Do they work together with dedicated hardware or are maybe some “soft” drivers, e.g. for networked audio?

I see from the log that the sample rate is set to 48kHz. Do your other drivers support that sample rate?
