In an attempt to fix the PSMobile project, this is a first fix.
The problem is that this property did not return a value in all different #if conditional branches (namely - in the last #elif, which PSMobile falls under since it is not Android or WinRT).
The fix is to simply return the private soundState field, as was before (i guess it was accidentally removed? )
SoundEffectInstance.State property getter returns a value in all #if …
A property getter that does not return anything is rather pointless.
