9. Troubleshooting

While using ERGO in WDM Mode, I’m not able to select a buffer size value from the Control Panel.

That is the expected behavior. To manually select a buffer size, select ASIO from the Control Panel.

I’m having problems loading the necessary ERGO drivers. I’m using a Mac OS X running AppleFWAudio2.1. What should I do?

Until a permanent fix is released, follow these instructions to install AppleFWAudio2.0.1:

Log onto http://developer.apple.com/sdk/ and download the FireWire SDK 24 for Mac OS X. A file will download called FireWireSDK24.dmg. Double click this file. From here, double click the FireWireSDK23.pkg file. This will launch the installer. Follow the instructions and prompts that appear.

Once installed, select Macintosh HD/Developer/ FireWireSDK23/FireWireComponents/FireWire Audio 2.0.1 and launch the installer by double clicking AppleFWAudio-2.0.1fc1-e8.pkg. Follow the instructions and prompts that appear. You will be prompted to reboot your computer.

Once your computer has rebooted, you may verify that the update has been performed from System Profiler by viewing the AppleFWAudio extension. Select the Apple icon and then About this Mac. From here, select the More Info button.

In the left hand pane under Software, select Extensions. After the Extensions list populates, read the version of AppleFWAudio that installed–which should be 2.0.1. ERGO drivers should now install properly.
