You should be able to use the setTrackTime(time) method.
There is also a getTrackTime() method that you can use as well.
I’m attaching a sample title.
Note that the sample title uses the HTML name of the object. Instead I suggest you use the script token %HTMLNAME% in place of the actual HTML name. To do this the action would have to be attached to the audio object (for the token to work).
getDisplayWindow().myAudioObject = %HTMLNAME%;
