Using setTimeOut, delay a callAS "multimedia_play"

Here is my ongoing quest -- recently SOLVED, up to the point of delaying display of an Alert, by using setTimeOut.  Now I seek to achieve delaying display of an RMA, similarly.

Here's where I need help.  My comprehension of ActionScript is still vague.  I have been able to, in a scrpt,   Play an RMA, by using an rm.callAS operation.  This works, as seen with 'First Clip' on the left side of attached document:

var aRM = this.getAnnotsRichMedia(0); // var used to ID any Clip on first page (PDF document page# minus 1)
//
var rm = aRM[0]; // get rich media annot for First Clip [RM List Position# minus 1]
//
if ( !rm.activated ) rm.activated=true; // activate the Clip-annot 
rm.callAS("multimedia_play"); // play First Clip, right away

The 'Second Clip', on the right side, is to play, following a 2.0 sec. delay:

var aRM = this.getAnnotsRichMedia(0); // var used to ID any Clip on first page (PDF document page# minus 1)
//
var rm = aRM[1]; // get rich media annot for Second Clip [RM List Position# minus 1]
//
if ( !rm.activated ) rm.activated=true; // activate the Clip-annot 
//
app.setTimeOut (rm.callAS("multimedia_play"), 2000 );  // Play Second Clip, after 2000 milliseconds

I can well imagine problems exist in my comingling of app.Methods, and callAS commands.

Comentary appreciated.
