With the 2.2.1 software, there are some rules that need to be followed for the Core Audio playback.

This is documented in our User Guide on page #61 and a portion is posted below for your convenience:
Playback
* You can simultaneously output audio from any of the following QuickTime-based applications when using MXO2 as the audio device:
- Apple Final Cut Pro
- Apple QuickTime Player
- Apple iTunes
- Apple GarageBand
- Apple Soundtrack Pro
* Note When using Apple QuickTime Player or Apple Garageband with any non-QuickTime application, you must close the current application before using MXO2 as the audio device in another application.

* When using any of the following non-QuickTime applications with any other application (QuickTime-based or not), you must stop playback in the current application before using MXO2 as the audio device in another application. You cannot output audio using MXO2 as the audio device from more than one of the following applications at a time:
- Avid Media Composer
- Adobe Premiere Pro
- Adobe After Effects
- Matrox Vetura Playback
* If you encounter audio issues when using MXO2 as your audio device, make sure that only one application that is using MXO2 as the audio device is running at any given time, or if applicable, remove MXO2 as the audio device in your Mac OS Sound settings.

When trying to determine the problem, please follow these rules and post if they were successful or not. It will help improve the efficiency of our troubleshooting.
