playbackmethod 1 means Initiates without any specific user interaction with Sound On

When to send it

Send 1 when the ad starts playing without the viewer doing anything and the sound is on from the first frame. On CTV this is the normal case: the viewer chose a program and the break plays with audio. Until AdCOM 1.0-202607 the label tied the value to a page load, which never described a television; the current wording covers any start without user interaction. In OpenRTB 2.0 to 2.4 the same value was called Auto-Play Sound On.

Buyers read 1 as audible, unprompted playback, the condition most instream video is priced on, and it usually travels with Video.plcmt 1. It is confused with 2, the muted version, and with 5, which also has sound on but waits until the player scrolls into view. A web player that autoplays muted should never send 1, since browsers block audible autoplay by default and buyers know it.
