Installing PlugIn on macOS 11.4 or Later

When installing Sound Control on 11.4 or later you are given the choice of installing either a User Audio Driver (recommended) or a System Audio Extension.

Installing the User Audio Driver is recommended. 

User Audio Driver (recommended)

• Supports AirPlay.
• Supports controlling displays on Apple Silicon Macs.

System Extension

• Doesn't support AirPlay.
• Doesn't support controlling displays on Apple Silicon Macs.

Using the System Extension requires changing your Mac's security settings.

The main advantage to using the System Extension is that all or your apps can be controlled without changing your Mac's default audio output device to Sound Control Output. If you do not have a specific reason to use the System Extension, we recommend the User Audio Driver. Please contact us if you have any questions.

Switching PlugIn Type

To change the installed PlugIn type you must first uninstall the previous plugin. In Sound Control's Preferences -> Support, click on the Uninstall... button. Make sure that only Static Z Sound Processor is selected for Uninstall. The next time you run Sound Control you will be able to choose the PlugIn type to install.

Installing System Audio Extension

Installing the System Audio Extension requires modifying the security settings for your Mac. See the following videos and instructions on how to accomplish this.
