Just as an example of what this might be - the newer codec _may_ require more resources than before (e.g. DMA channels), and if those extra resources aren't made available (typically done in the .cfg script), the creation may fail.
You may be able to learn more about the exact cause of the create failure by: 1. Enabling trace in Framework Components (http://processors.wiki.ti.com/index.php/Trace_in_Framework_Components) 2. Displaying that trace via CE_DEBUG (http://processors.wiki.ti.com/index.php/CE_DEBUG) You might also dig through the codec data sheets and/or users guide. Sometimes those show what resource requirements the codecs have - you might get lucky and find differences there, too.
