Internal speakers: Stereo or mono?

[Marcel]

Hello,

I always thought the Freerunner's internal speaker(s?) were stereo ones. (And 
this was at least planned once for sure!) Now as I'm more or less actively 
using it as an mp3 player, I noticed that only the left one (according to the 
openings, looking at the FR from bottom) gives some noise. The effect is 
obvious if you close the openings with a finger, the volume only really 
decreases when closing the left one. Looking at the wiki it says the 
Freerunner's speaker is monophonic, so just *one* instead of two.
Can someone clear this up?
