Pistonheads BMW M3 Sound file problems

[notthehamster]

Is it just me that can't hear the sound files under the above banner? I tried the latest level of Firefox. I then tried IE, which said that some mime files were in use elsewher and would I like IE to have them back, to which I said yes. Still no dice. Laptop is a newish centrino duo Vaio so it's not as though the hardware is dated.
