I thought it's already been discussed that the chip has the capability of directional sound. If this is the case, it is theoretically possible to achieve surround sound. Directional sound can be bounced off walls more efficiently and precisely than standard sound waves.

We have a workmate in the office with a directional speaker. When he first got it, we played tricks on other workmates 20 to 30 metres away by aiming the speaker at the ceiling at an angle that would allow the sound to bounce off the ceiling and on top of his head.

The result? No one could hear the music except him. He though it was coming from the floor upstairs, but was wondering why it was so clear. Neat trick!
