Mac and Audio
This applies to Mac OS 10.7 and MXWendler version 4.2 and above
You reinstalled / upgraded MXWendler - even into another folder - and suddenly USB or FireWire audio does not work anymore.
There are three known possible solutions:
1. Reinstall the USB/FireWire audio driver
2. Go to System Settings, switch to internal speaker and back
3. Create a new User Account, and open the audio device under this account
