Steinberg UR22C with Apple Mac M2 Issue ( "Audio Hardware Removed")


i have a problem with my sound card UR22C and Mac M2. When I work in Cubase 12, sometimes my connection drops and it automatically switches to built-in audio. It repeats itself several times until I have to disconnect the sound card and reset it. The system will write me a message, via photo. It’s pretty annoying. Same problem when I turn Rosetta on or off. Can anyone think of what it could be? If this is a problem in system security? Bad compatibility?

Thank you very much.

Hi and welcome to the forum,

I’m not sure, if this is also the case on Mac, but verify, if the USB port doesn’t switch to a sleep mode, if there is no trafic.


thanks for advice. I will try check that, but this problem appears even, when I recording guitar or listening/editing. So it must go to a sleep mode in few seconds/minutes…

Sometimes it works fine, without any problems but sometimes, especially when I have more tracks and plugins in the project, when there is a big load on performance, but I don’t know if it can be related. If it had a bad effect on performance I would see it on the performance meter or cubase would crash when working or playing…?

Thanks for any help :slight_smile:


It sounds wierd to me.

Could you also try to increase the Buffer Size, just to don’t overload it?

I increase it when i just mixing, but when recording, I don’t know, it seems like there is bad contact of the usb cable between the card and the PC, but when I try to move it mechanically, there is no interruption…but the fact is that the same window pops up when I disconnect the cable.


I uploaded a video just to be sure, sorry for the format, I don’t know how else to put the video here


I see. This is definitely wierd.

I would try to rename/remove Cubase preferenes and maybe even reinstall Cubase. And I would definitely try to reinstall the driver.

Can you try on other USB port, please?

Cubase Preferences folders are:
Mac: ~/Library/Preferences/Cubase X
Win: %appData% \Steinberg\Cubase X_64

Where the X is the Cubase version (for example 13).

Hello Kuzel,
Just for troubleshooting purposes, you can plug the UR22C with a power adapter separately .
Also do you have Asio guard enabled?
If the interface connection is on the Thunderbolt port, you can try the USB port instead.

Just mentioning a few possibilities that might solve the issue :slight_smile:


I just try reinstall and update Interface Driver. Also in recovery mode, I changed security policy according to installation guide. I have enabled Asio Driver, is it good to be enabled or disabled in this case? Maybe I will reinstall also Cubase, but for now I will see if it will works…When I reinstall driver, this window is showed in Control Panel…Do you think this might have something to do with it?
