The default interface for the RadioLab audio is seen below in Figure 1. On some devices, when the play button is selected there is no audio and the browser may crash when the play button is left "on". If this happens, begin again from scratch. Reload the Radiolab page. Do not use the triangular play button. Instead, select the "Listen" tab just below the play button.
When you click on the "Listen" tab, it will bring up the window seen below in Figure 2. NOTE: You may find that you have to click the pause button and then the play button to get it to play properly.
This should work in most cases. If it doesn't, then your device is not designed to support the player. Sorry.
