Some testing notes for OS10 for the XO-1

[John Maloney]

Hi, Steven.

The USB-serial cable that comes with the Scratch Sensor board needs a  
driver from Prolifix. That driver used to be included in the builds,  
but perhaps it was accidentally dropped?

If you use a supported USB-serial adaptor cable, then I think the  
ScratchBoard will work.

I just got a report that sound playback is rough on XO 1.5:

   http://dev.laptop.org/ticket/9375

I'm guessing this is caused by a switch from ALSA to PulseAudio. We've  
seen that on Ubuntu;  we still working to resolve the problem.  
PulseAudio itself has some buffering issues, although it appears that  
folks are working on those. The problems tend to show up more in  
applications where sounds are triggered dynamically, such as Scratch,  
EToys, and games, vs. playing music.
