[Mac-OS-X] patch addressing issues with USB-2 audio devices

Depending on the setup, it may happen that there is no audio playback available when working on Mac OS X 10.6.x or when using a USB-2 audio interface. In addition to that problems might occur when changing the sample rate and even general compatibility issues between software and hardware can come up.

Affected are:

Cubase 6/Artist 6.0.0
Cubase Essential 5.1.x
Cubase AI 5.1.x
Cubase LE 5.1.x
Cubase 5.5.x
Cubase Studio 5.5.x


In case you are working with the aforementioned setup and one of these applications, please download the patch file.


Please note that all upcoming updates (e.g. Cubase 5.5.3 and Cubase 6.0.1) will include this fix and thus this patch file won’t be needed anymore.
