Source-Nexus I/O devices missing after reboot
This article contains troubleshooting information
Some or all Source-Nexus I/O devices created in Source-Nexus Control Panel are missing after a reboot
Source-Nexus Control Panel | 1.0 | Mac
After a reboot, some or all of the Source-Nexus I/O devices created using Source-Nexus Control Panel are no longer available.
The Source-Nexus I/O device settings are saved in /Library/Preferences/Audio/com.apple.audio.SystemSettings.plist
If this file does not exist, then the device settings will not be saved nor loaded properly after a reboot.
Create the missing folder and preference file.
To create the file the user would need the administrator permissions. Open the Terminal app and run the following commands:
- These will create the Audio folder:
sudo mkdir /Library/Preferences/Audio
sudo chown root:_coreaudiod /Library/Preferences/Audio
- These will create the System Settings file
sudo touch /Library/Preferences/Audio/com.apple.audio.SystemSettings.plist
sudo chown _coreaudiod:_coreaudiod /Library/Preferences/Audio/com.apple.audio.SystemSettings.plist
sudo chmod g+w /Library/Preferences/Audio/com.apple.audio.SystemSettings.plist
After this is done, users should try creating new devices via Source-Nexus Control Panel and restarting the computer.
