Discussion
This property performs validation on the formats represented by the audio in the description. It finds the first Audio for which the current system has a valid decoder. This API is specific to audio format descriptions, and will return NULL if called with a non-audio format description. It may also return NULL if there is no suitable decoder available on the current system for this audio format.
