Creative subtypes (audio and video) value 9 means DAAST 1.0
DAAST 1.0 inline, the separate audio template; audio support moved into VAST as of 4.1.
When to send it
Send 9 in Audio.protocols only if the audio player still parses DAAST 1.0 (Digital Audio Ad Serving Template), the separate audio format IAB Tech Lab published before folding audio support into VAST 4.1. OpenRTB 2.4 added the value when it introduced the Audio object.
Audio buyers now mostly return VAST 4.1 or later, so new audio integrations should list 11 and above, and a list with DAAST alone limits demand to buyers that still produce it. It is confused with 10 (DAAST 1.0 Wrapper), and with the VAST values when a seller puts DAAST into Video.protocols by mistake.
