I'm not sure what Halo changes Steve suggest...
Fix is quite easy if you know your way around the Etoys system.
Just comment out the SoundPlayer initialize in the class method, see below.
A change set with this fix can be attached to the project.


SoundPlayer class>>startUpWithSound:
 startUpWithSound: aSound
       "Start up the player process."

+       "SoundPlayer initialize."
-       SoundPlayer initialize.
               startPlayerProcessBufferSize: (BufferMSecs *
SamplingRate) // 1000
               rate: SamplingRate
               stereo: Stereo
               sound: aSound.
