Does the audio system have the ability to flag that the microphone is 
mono? If so, that seems preferable to pushing the same data through both 
channels. Perhaps it is already doing this and the activities are 
misbehaving? Measure should certainly have the ability to turn off one 
channel it either shows the same data or no data when using the microphone.

Sorry, didn't get to this during the week. Hopefully this week will be 
better. The version numbers are in the power logs (we put the laptop 
names into the comment field). Hoiho had

ECVER: 0.4.03
OFWVER: CL2   Q4D13  Q4D

What would you like me to do next? I have a serial cable for the cpu 
serial port.

Poppy Copy has working wifi on the olpc-au builds. It does have some
