DVD - A is pure audio without any encoding in surround formats (i.e. DTS or Dolby D).
If you have Dolby Digital appearing, then it seems you have your DVD-A
connected via a coax/Toslink cable. You are not hearing DVD-A you are hearing DVD video via the video sound encoding.
DVD-A and SACD are analog ouput only unless you have a Denon Link or IEEE-1394 connection. The Pioneer 912 supports neither.
What DVD Audio player do you have hooked up to the receiver and how is it connected?
