7.4.2. Response Format
There are two types of response from the codec to the controller. Solicited Responses are returned by the
codec in response to a current command verb. The codec will send Solicited Response data in the next
frame, without regard to the Set (Write) or Get (Read) command. The 32-bit Response is interpreted by
software, opaque to the controller.
Unsolicited Responses are sent by the codec independently of software requests. Jack Detection or GPI
status information can be actively delivered to the controller and interpreted by software. The ‘Tag’ in
Bit[31:28] is used to identify unsolicited events. This tag is undefined in the HDA specifications.
