well, I could be watching a show- and a voice-over will occasionally say what is happening- "A man is driving the car. he is wearing a dark suit and tie. the left window is rolled down"
I'm not 100% sure where the sound is coming from, it's coming from the same speakers as all the other sound, no doubt... I've eliminated the TV, so it's either the reciever, or the sound system itself. I suspect the sound system, but I cannot seem to get into it's settings menu.
