The controller is determined by the player used. Run mode has a Trivantis player. There is one for Quicktime and one for ??? and one for ??? ... The player is determined by the browser and other software on your machine. There was some discussion a while back about using something from Flash or putting the audio into Flash. Not sure. Try searching the forum using Search in the upper left. Not sure what to put in the search box though.If all you want to do is start and stop, then you can use actions attached to buttons. Most people want more though like pause and a slider. Pause did not work the last time I tried. It may now.
