CoreAudio driver went missing
This error message was introduced in the SoundID Reference standalone app since version 5.7.3 to signal a failure to communicate with CoreAudio for various reasons and conditions. Our developers have included a button directly in the error message to offer a quick resolution.
What can be done to fix this?
If the error persists, there is a list of actions and workarounds that could potentially help.
- Click on the 'Restart CoreAudio' button within the error message. If you're unable to restart the engine using this button for any reason, you can initiate it via Terminal manually:
- Launch the Terminal app
- Execute the following command:
sudo launchctl kickstart -kp system/com.apple.audio.coreaudiod
IMPORTANT! Before doing this, make sure to switch off speakers/headphones (or turn down the volume completely,) and shut down any DAW or other music production software
- Restart the playback engine: SoundID Reference app > Output Panel > '…' > Device settings > Restart playback engine
- Quit and relaunch the SoundID Reference app: How to fully quit the SoundID Reference app?
- Clear the configuration data: Deleting the config file in SoundID Reference standalone app
- Update the drivers of the interface to the latest version available
- Fully uninstall SoundID Reference. Then reinstall the latest version - download here
- Uninstall other Virtual Devices active on your machine (Blackhole, GroundControl, LoopBack, etc.). There may be a clash between our Virtual Output Device and another. If it then works, it's worth adding them back one by one, to see which one is the culprit.
