In fact, I think I'd prefer if the original poster took this approach, rather
than attempting a separate command.  This ensures that the sound only
reaches the channel when it makes sense and not in the middle of some other
set of prompts.

Typically, if you are looking to divert the channel from AMI, you'd want to
use the Redirect command, anyway, to send the channel to a set of events,
not just a single Playback.
