_raw_body_() retuning incorrect packet body data

[thunderdanthaman]

._raw_body() returns data with the CSDW repeated at the beginning and clips last 4 bytes of data..
CH11 - It appears CSDW is specific to the data packet body and is a 32bits.. Have only been pulling PCM data but perhaps seeking 40 or 28? or else exclude concatenating CSDW on return?

chapter10/packet.py

# Pull raw bytes if not a message-based packet
        else:
            self.buffer.seek(36 if self.secondary_header else 24)
            body = self.buffer.read(self.data_length - 4)
        return self.csdw_format.pack(self.__dict__) + body
