Media starts playing

GLWin automatically starts reading aloud (or playing the associated media for) the content in the active Home tab.
My experience has shown me that this happens when the system speaker changes (I often have bluetooth devices connected).
Not only does it play unsolicited, if I press Pause (on the Media tab), it begins again within a few seconds.

Any wisdom you can share? If it's a glitch, I'll report it.

Thanks,
D.G.
