[SoaS] SoaS 32 is silent?

[James Cameron]

Good, that makes it not-Sugar.  Get it fixed on Workstation is your
best bet.

I've seen this kind of thing happen with laptops that have HDMI output
capability.  Audio is being clocked out a disconnected port.

Sugar predates PulseAudio.  Sugar has no support for anything other
than ALSA.  An opportunity.  GStreamer as used by Speak will use
PulseAudio if available.
