[flexcoders] Access of undefined property flash.media.sound

[Shaq]

The code below is pulled from the Flex 3 manual but I am unable to get
it to compile correctly using Flex 3.  Can anyone provide any insight
as to why the code below raises the following errors:
1120: Access of undefined property onSoundLoaded.
1120: Access of undefined property req.
1120: Access of undefined property s.

Any help would be greatly appreciated.
