I can't use my built-in audio as my output

I’m not an American so please don’t mind if I type some sentences that are not that pleasant for you. :sweat:
Is there anyone who faced the same issue just like me.
I set up my macbook pro built-in audio as my output.
Sometimes it can be used normally.
But it keeps showing up a window telling me that cubase can’t find my built-in audio.
I’d like to know if there is a solution for that.
Did anybody have the issue before?
Thank you for helping me. :sob:


I’m using the built-in audio without issues here.

What macOS version do you run, please?

Here it is. Thank you. :bowing_woman:t2:


What macOS version do you use, please?

Could you try to restart your Mac, please? There is also a way, how to reset the CoreAudio on the system level. I would try this.

Oops. Sorry I just misunderstood what you said.
I use mac 10.14.6
And I tried the two methods after seeing your reply.
It seems that the error window still shows up but the frequency reduces.
By the way, thank you for your reply. :sob:


Does the message appear while starting Cubase only or anytime?

Do you have any Bluetooth Audio Device, which tried to connect to your system?

It appears anytime.
And I 'm not sure the problem is input or output anymore.
I checked my audio connection.
It seems cubase can’t find my right built-in input.
And the left one is sometimes missing, but usually normal.
I have connected it with my airpods, but the window still appears.
