The system property audio3d.simultaneouslocations must
return at least 1, according to the JSR-234 specification. In the S60 AMMS
implementation this returns the value 4, as the underlying audio adaptation
in the platform is capable of handling 4 separate 3D audio streams. When using
AMMS, you should check this value, and try to code the application according
to it (instead of first trying to create, for example, 10 different 3D audio
locations).
