[SoaS] [Sugar-devel] SoaS 32 is silent?

[Alex Perez]

Correct, this is a function of multiple audio outputs, and how they are 
enumerated. I have verified that SoaS boots and runs, with sound and no 
changes required, on an old iMac5,2, form 2007. As an aside, this is one 
of those weird Apple-manufactured 32-bit EFI machines (but 64-bit CPUs).
