I was just wondering about this. The PSP has 4 speakers holes. and yet, the sound only comes out of the bottom of the PSP and not the top. Upon taking off my faceplate multiple times, i find no speakers. why are these holes here? diagrams of the psp always show the speakers to be the top 2 holes. many cases and skins put the speaker holes on the top and NOT on the bottom. i dunno, does everybody's psp do this? Do some people have sound come out of all 4 holes?
