Abstract
Systems and methods for overriding hardwired responses of a codec to High Definition Audio (HDA) verbs that are received from an HDA controller. In one embodiment, an HDA codec is configured to store one or more overriding responses, each of which is associated with a corresponding HDA verb. When an HDA verb is received by the codec, the codec determines whether the verb is associated with one of the overriding responses. If the verb is associated with one of the overriding responses, the overriding response is returned to the HDA controller. If the first HDA verb is not associated with one of the stored overriding responses, provide a hardwired response associated with the first HDA verb to the HDA bus. Overriding responses can be returned for unsupported verbs only, or for any verbs that prompt responses.
